Connecting a motion sensor to the lamp or lamp or lamp, people avoid high electricity costs and, in effect, they pay for a utility service. The device that locks the movement of objects is a convenient device, because it provides a unique opportunity to enable and turn off the light automatic.

Principle of operation and use of the sensor

Motion sensor is a device that "notices" changes in the location of objects in space and responds to the launch of the necessary actions. If the device is connected to the electrical system, then in response to the movement of a person, the sensor closes the chain and gives light. This reaction is the result of the transformation of the heat field, because its temperature is raised due to air fluctuations.

However, the principle of operation of the motion sensor may be different. Therefore, the device is infrared, ultrasound, microwave and combined. Only an infrared sensor reacts to changing the warm field. And the ultrasound and microwave adaptation functions due to the receipt of sound oscillations. The sensor who catches ultrasound is considered the most perfect, as it scans moving even through the walls. The combined device captures several types of radiation.

The device fixing motion is used as a device to help save on electricity. But the sensor is good not only to the fact that turns off the light, if forget to make the owner of the house and children running from one room to another. The device eliminates the need to grope switch in the evening and night hours or allows you to abandon the switching apparatus.

Selection of device

In order for the motion sensor, including the light, it is triggered in time, it must be installed correctly. It should be guided by some advice:

Connection schemes

To connect the motion sensor to the network and the lamp, you must first figure out the installation scheme. Otherwise, you can get confused, because the device is 3 of the contact: zero, input and output to the lighting device.

Figure 1 - Connection without a switch, Figure 2 - Connecting with a switch, dividing light, Figure 3 - Connecting with a switch that gives light

When connecting the motion sensor to the lighting system, you can go three ways:

• Attach the device to the electrical network without a switch, if you need to make the sensor fully responsible for the inclusion and shutdown of the light, which makes it sense if necessary to illuminate the receiving territory or pool.
• Together with the instrument capturing air fluctuations, use the switch in the room, which is forcibly extinguished in the room light, and this means that the lamp must be connected to the electric network bypassing the motion sensor.
• Adjust the lighting circuit of the lighting system not only to the device that automatically serves light, but also switch, when you click on which the light will go out and will not light up due to movements made in a dream.

Instructions for connecting the motion sensor to control the lighting

The device that feeds the electric current into the lighting device is only after capturing the movement, it will earn if it is installed as follows:

Sometimes the motion sensor is required to connect together with the switch. This task must be performed so that the switch is connected with the lighting device, and with the motion sensor. This can be done as follows:

1. Find a wire that reaches from the lamp to the switch.
2. Connect another one to the detected wire, sent to the red contact of the motion sensor.
3. Take the wire on the other side of the switch and insert the device in the brown contact automatically turning on the light.
4. Stretch wire belonging to the lamp to the motion sensor terminal.

Solution of possible errors

When installing a device that includes the light after trapping down the movements of a person, you can assume an error that consists in creating a poor contact at zero wire. This happens if the wire is inserted into the terminal together with the construction garbage or not live, which leads to the formation of a tight layer of carbon black, considerable heating, oxidation and contact loss. If the sensor does not work, the wires need to be checked and read or live if necessary.

The sensor malfunction may be the consequence of deformation and breakdown of aluminum veins. To believe that it is necessary to apply a voltmeter - closer to the covers to the terminals. True, the device may not work even in the case of a voltage detection. In such a situation, it is necessary to replace the old lamp to a new one, because, most likely, the problem lies in the abnormal of the channel thread in the lighting device.

Sometimes people who have installed a motion sensor in the room face the following problem: the light will not turn off, despite the fact that the device reacting to human movement is properly. To deal with this problem in the device, you need to check the time period. Probably, this value is too big and does not give the output contact responsible for the operation of the lamp, open. In this case, it is necessary to slightly reduce the time delay on triggering.

Adjusting the operation of the motion sensor to turn on / off light

On the device first it is necessary to put up time. The sensor allows you to select the gap from a second to 10 minutes. Decide with the time it will be easier if you listen to the following advice:

• the optimal period of filing light on the staircase is a few minutes, because it rarely delay longer;
• a normal period of time for feeding light into the utility room is 10-15 minutes, because of such a room often has something to take.

On the sensor, it is assumed to set the trigger delay after fixing the motion of the object. This value can be from a few seconds to 10 minutes and is determined by how quickly the person moves. For example, the corridor crosses quickly, so it is better to mount the sensor with the abbreviated parameter "TIME".

The level of illumination dependent on the LUX regulator should be debugged in such a way that the sensor performs its task to the moments when the room is illuminated less than usual. The room where a lot of light penetrates out windows is recommended to equip the motion sensor with the "LUX" regulator set to the initial or average position.

The sensitivity of the device that runs certain actions in response to the movement of a person is under the control of the "SENS" regulator. This magnitude is influenced by the remotence of the device from the moving object and the weight of a person who caused the sensor to earn. Therefore, in the case of switching on the light sensor, no cause is required to make a sensor less sensitive. And about increasing the reaction indicator of the device should be thought out only in the absence of actions from the sensor during the passage by him by him.

The motion sensor has a complex design that you have to adjust for special conditions of operation. Ignoring rules is fraught with the fact that the device will work against the desires of the room.

The use of the motion sensor to activate the light at the time of approaching the lamp significantly increases the level of comfort in the home / office / apartment. The miniature instrument is heading for you by the system, allowing you to take care of such trifles. Reduced electricity consumption, and you can easily install it with your own hands.

Economical on all sides by the device should be taken. Agree? We will tell you how to connect the motion sensor to the light bulb. In the article submitted, the article presents technological rules and schemes available to the beginning of the electrician. Listed options are listed, the specificity of the setting is described.

The main purpose of the motion sensor is the switching of an electrical network. It can work both with an active load in the chain and with active inductive. Any movement in the control area primarily launches the process of determining the level of illumination (if such a function is provided in the device).

If the indicator below the set trigger threshold, the device closes the contacts and turns on the lamp. Thus, the detector can work both in the night, and during the daytime. Install the trigger threshold using regulators, it can be from 3 to 2,000 LCs.

In everyday life, the devices of which are based on the capture of electromagnetic wave oscillations in the infrared spectrum. The time through which the detector works, in the event of a detection of a moving object, is also configured.

Turning the regulator, the shutter speed is set. At different models, the delay time can be adjusted from 10 seconds to 7-15 minutes (a small error is allowed).

The work of detector devices is based on the detection of motion or at identifying a person's stay in the review zone

Literators of competent selection

Different models can have a different purpose. Some are intended only for controlling inner lighting devices, others are more universal and can be used for electrical appliances schemes with alarm devices, s.

Sensors can be with a limited and circular overview, have different angles of horizontal and vertical observation. Devices for connecting the wall control the zone at an angle of 110-120 ° or 180 ° horizontally and 15-20 ° vertically.

Models with a moving organ of review significantly facilitate the setting, but stationary do not have such an opportunity, so they need to carefully choose the placement location.

In models with a limited overview, the viewing angle may vary and make up from several units to hundreds of degrees. When choosing a device, you must consider what area will be able to control the device

Circular overview detectors can cover a controlled zone at an angle of 360 ° horizontally. Their viewing area has a cone form that expanding the book. Despite the large control zone, not viewed sites (outside the radius, in the corners) in the room still remain.

To install the sensor on the street or in rooms with high humidity it is necessary to choose a device with high on external factors (dust, moisture).

For example, devices with a protective degree of IP20 are permissible to use only in interior with normal humidity, with IP33 it is possible to install on the street - on the terrace, porch, gazebo. With IP44, you can mount on the street, but to protect the visor from the drops of water droplets during atmospheric precipitation.

You can buy a ready-made complex from. With the peculiarities of its choice and the installation will introduce the article recommended by us.

Placement and method of orientation

General rules for setting sensors are as follows:

• the height of the installation above the observed surface can be from 2.5 to 4 m (the parameter depends on the device model);
• when choosing a place for installation, take into account the fact that the detector is more sensitive to the movement, which occurs across the observation area;
• The total load capacity of the lamps is limited and can be, for example, from 60 to 1200 W for incandescent bulbs and from 0 to 600 W for fluorescent illuminators.

The sensitivity of the detector also affects the temperature and temperature. The range of temperature values \u200b\u200bin which the device normally performs its functions - from -20 to 40 ° C.

Ways to install traffic sensors using the example of TDM Elektrik devices: DDPT-01 mounted in the cartridge; E27, DDT-03, DDT-02, DDT-01 are installed in the mounting hole for point luminaires (the diameter of different devices is different and can be 40-65 mm); DDSK-01 can be mounted in the wall, ceiling, luminaire case

It is forbidden to install lamps:

• on vibrating surfaces;
• near fans, air conditioners;
• on glossy white surfaces of the walls;
• near heat sources -, lamps;
• on the surface located under the right rays of the sun.

To avoid false response, avoid infrared detector sources of electromagnetic waves, wind and thermal flows.

It is also impossible to fall into the zone of action - a gradually cooled thread will lead to a detector response, since it will respond to the inclusion of its temperature.

So it can continue until infinity - the light will turn on and off. False response can also occur in windy weather due to branches.

When choosing a place of installation and location of the sensor itself, it is necessary to consider: installation height, ambient temperature, make sure there is no no interference

How to install the device and connect it to the lamp?

To begin with, consider the installation of the motion sensor on the example of models that are installed in the holes intended for point lamps.

Installation sequence Next:

1. Turn off the voltage in the power grid.
2. Remove the protective plastic lid (Fig. 1).
3. Connect the conductors (Fig. 2). Connection diagram The manufacturer indicates the instrument itself and in the device passport.
4. Figure springs-locks, directing them up (Fig. 3).
5. Install the sensor in the prepared hole (Fig. 4) - the springs will fix its position.

Motion sensors in the mounting of motion sensors that are installed in the holes for point illuminators are indicated on the back side. It can be somewhat different from different series of devices.

It is easier to establish a sensor that screws into the cartridge. Then the light bulb is screwed into it. In this case, it is necessary to use only those lamps that are not more powerful than indicated in the device passport. It is advisable to purchase, designed to work in a tandem with detectors.

To establish a remote sensor in the ceiling, wall or luminaire case, you must start the device in the prepared hole, fasten the body to the mounting surface with the help of screws. Next, you need to turn off the power supply and connect the phase and zero conductor of the feed cable to the terminals according to the scheme.

Testing and setting the motion sensor

Each device has a minimum of two regulators. Testing and setting is performed on two main parameters - the duration of the glow (TIME) and trigger sensitivity (LUX). The first indicator means a period of time to which the sensor leaves the lamp turned on.

With each recognized movement, the countdown of the duration of the glow begins first. It can be customized by the user for a period of 10 s to 4 minutes.

The sensitivity of the device is also customizable value. With it, it can be corrected, with what kind of natural lighting will be turned on. Thus, you can adjust the inclusion of the lamp during and day, and the night or only at night.

Running the motion sensor to work, carry out its mandatory testing. To do this, set the light level control to the day lighting position. The time control regulator is set to minimum.

After connecting to the power, you need to wait about 30 seconds - the sensor will work and turn on the lighting also for 30 seconds. Next, you should send a sensor sensor to the zone that should be under observation, check the sensitivity and radius of action.

Testing whether the interval of the response time and the lamp operation with the parameters set. You also check the operation of the device at night and finally set comfortable parameters for yourself.

More complex device designs, which are used in security purposes, have in their design yet regulator of the range (SENS). With it, the sensitivity zone is set. Sensors also equip the integrated microphone with the noise level control (MIC), in which the device must work.

The last two regulators are rarely used for inexpensive sensors, since their functionality in domestic conditions is rarely in demand.

Options for connecting the IR device to the lamp

Using various connection schemes and additional devices, you can achieve a wider functionality of the motion sensor. For example, expand the controlled zone, turn off the automatic control of the lighting system or temporarily control the lighting group without the participation of the motion sensor, etc.

Connection to control without switch

A diagram consisting of a lamp and detector is the simplest. It is applied by the manufacturer on the back of the device or is described in the attached instruction.

When arranging elongated premises, along the tracks in the yard or around the perimeter of the building of one device, it is not enough to control the lighting - its limited review does not allow this to do.

In such cases, two or more detector use. Their terminals are connected by parallel diagram, and then lead to the lamp.

Connecting to the light bulb with switch

To disable the automatic switching system, which runs on the basis of the motion detector, a switch is added to the working circuit. Connect it on a plot of an incoming power cable before the sensor.

In the enabled position of the switch, the scheme works just as if it was drawn up without it. When it is turned off, the motion sensor module is completely de-energized and the system does not work.

If it is necessary that when a person is located in the room, the light burned, while finding it in a fixed posture did not lead to the disconnection of lighting, then use the following scheme.

The switch is connected to the input and output phase conductor of the sensor - thus, a branch of the electrical network is created bypassing the main area. Now, using a switch, you can enable lighting that will not depend on motor activity in the controlled zone.

In this scheme, the switch is shut down the electrical circuit plot through the lighting control sensor. This connection creates more comfort when controlling the lighting device.

Tested in practice the circuit of connecting the lighting control device using the switch disassembled and, read which we really advise.

Video # 2. Two options for connecting the sensor to the lamp with switch:

The method of connecting the motion sensor to the lamp largely depends on the purposes that are planned to be achieved. Based on whether you need to organize automatic lighting in an apartment or on the street, near a guarded building or garage, pick up the device and the working circuit.

Want to talk about how the motion sensor connected to the light bulb with their own hands? Have useful information on the topic that can help site visitors? Please write comments in the box below, place a photo in it and ask questions.

Economical and at the same time functional, it urgently recommended that you set the motion sensor on the spotlights. This device will allow you to automate the backlight system and include it not only when the dark occurs, but in the event that movement will be recorded in the detection zone. However, it is not always possible to configure the way you want, with the result that the sensor works at the slightest vibration of branches or when it's not too dark on the street. That is why for our readers, we have prepared a detailed instruction in which you have accessantly explained how to configure the motion sensor for lighting with two and three regulators.

How can I regulate the detector?

In modern motion sensors (DD), you can configure sensitivity, illumination, light off delay time and installation angle.

All these parameters, with proper configuration, save up to 50% of electricity, which is a very significant indicator. However, it should be immediately noted that there are no three regulator in all motion sensors. In old models, you can only adjust two parameters - the delay time and sensitivity or the delay time and the level of illumination, as in the photo below:

Sensor Review

Now we will analyze individually how to configure the motion sensor on the spotlight or other variant of the lamp.

Settings

Installation Angle

The first thing to do is to properly adjust the DD detection zone. In modern models of lamps, detectors are represented by individual elements fixed on the hinge. Here you just have to set up in such a way that the infrared rays be aimed at the maximum possible detection area. A not only installation angle plays an important role here, but also the height in which you decide. The optimal and most unsuccessful installation methods are considered in the schemes below:

Sensitivity

The second parameter you must configure is a sensitivity that is indicated on the "SENS" housing. As a rule, a wheel with a range from Min (Low or -) to Max (High or +) is used to adjust. Setting the sensor sensitivity of the most complex. You must adjust the parameter so that the detector does not work on small animals, but at the same time included the light when a person is detected. In this case, it is recommended to immediately configure Sens to the maximum, wait until the flashlight turns off and check how the sensor will trigger.

Gradually, you will need to reduce the sensitivity until you find the Golden Middle. We draw your attention to the fact that if you have a big dog in the yard, perform the sensor setting so that it does not react to it, it is unlikely to succeed.

Next setting is the light threshold marked on the LUX case. This parameter is necessary in order to adjust the sensor to switch on light only when dark. For example, it is why the lighting is turned on when the movement is detected into a bright time of the day, it still will not give anything. When first configuration, it is recommended to set the maximum LUX value and upon the occurrence of the evening, adjust the right time at which the sensor will trigger.

If there is no LUX controller on your detector, you can additionally. In this case, it turns out anyway to configure the searchlight so that it turns on only at night.

Delay time

Well, the last parameter is the inclusion delay, indicated "TIME". Time to configure the easiest things, the range can range from 5 seconds to 10 minutes. Here you already have to decide for what time it is better to set a delay. There are sensors that, with each new inclusion, the delay time increases. When initially configured, it is recommended to set this regulator to a minimum mark so that you can quickly check the parameters.

Also a few useful information you can find out by viewing this video:

How to perform adjustment

That's all I wanted to tell you how to configure the motion sensor for lighting. Such detectors can be installed not only on the street, but even in the apartment, for example, on the staircase in the entrance. We hope that the instructions for setting up the detector with two and three regulators was useful for you!

On the principle of work, lighting sensor is arranged so: A photosensitive element that is installed in the sensors is able to change its resistance, depending on the lighting. In the form of this element, the photoresistor is usually performed.

Then, the calibration scheme is entered into action, through which the signal from the photoresistor goes to the transistor.

The transistor circuit has a relay. The transistor, using a relay closes a network and a lamp or a searchlight, which is connected to the network, starts glowing. In the article, the principle of operation will be described in more detail.

How to connect the lighting sensor.

It is worth noting that the circuit of connecting the lighting sensor is identical to the motion sensor connection scheme.

Proper installation of the lighting sensor.

Of course, to connect and configure the case is not difficult, it is much more difficult to determine the right place to install the sensor. He told me a familiar story as he had a street lamp in the area, then turned on, turned off.

And after the onset of complete darkness on the street, he finally began to work normally. Do you know what was the case?

The light sensor was installed directly under the flashlight. Because of this, when the dark occurs, it turned on the flashlight, recognized that light and turned off. Such a situation can happen to everyone. But so that this is not, you need to not install light sensors, next to the light source.

Setting the motion sensor.

When you calibrate the sensor, then use a black bag, it comes in a set.

The only thing that can be configured from this sensor is the light regulator. They can set the level when the relay will trigger. The details of the adjustment and settings are described below.

LXP-01 light sensor, can be attributed to the simplest. It does not allow anything about it to change and configure. There are more advanced sensors, you can configure the trigger delay.

Appearance of motion sensor.

Sensor LXP-02.

Purpose of sensor outputs:

1. Red need to summarize the load

2. Blue, maybe green, it is zero

3. Brown (black) - power sensor.

If you remove a white case, then we will see the sensor scheme located on the printed circuit board.

For a simple calculation of the required number of lamps, useCalculator calculating the number of lamps.

The sensor contains the DE3F-N-A relay at 24 VDC. Current contact 10a. This value determines the maximum load on which the sensor is capable. That is, 10 to 220, there will be 2,2kW. Similarly, stated in the instructions.

But my opinion: to this sensor, you should not connect more than 4 amps. All that is higher only through the intermediate starter.

Photograph of motion sensor board.

These are the tracks, with a layer of solder on them, it is them - more often the rest are burning when overloading, incorrectly connected K3. If this happens, the relay will also have to replace.

According to the instructions, the LXP-03 lighting sensor is able to switch currents 25a. The board states that the current of the relay 30a, most likely the manufacturers decided to be reinsured, and I, in this regard, did not go far from them. I decided to limit the current on the 16a.

For lighting is also with a margin.

Well, for dessert - all the most interesting:

The presented scheme is taken from that board, which is shown at the beginning of the article. Now the manufacturer actively improves and changes its device, so some data may change.

In principle, all the same:

The supply voltage of 220V flows through zero and terminals. Zero - N, Terminals - L.

If you change the phase and zero in some places, or at all turn off zero, not the phase, then nothing terrible will not happen. But it is extremely recommended to do it, security has not yet been canceled.

The voltage is straightened using a diode bridge, 4 diode type 1N4007. The electrolytic capacitor corresponds to the voltage filtration, the stabilization occurs at + 22 ... 24V, for this, a stabilion of type 1N4748 is installed.

The remaining part of the scheme is powered by constant voltage. It is arranged as follows: at the output of the resistive divider 68k - VR - the photoresistor is created voltage, which is completely reverse the level of lighting. That is the device that configures the response level is a VR stroke resistor with 1 MΩ resistance.

What exactly put in such schemas: a photoresistor or photodiode is unknown. Most likely a photoresistor, but a similar photodiode can also stand there.

If you want to economically and efficiently spend electricity, then turn the controller clockwise to the maximum, so the lighting sensor will only work when the complete darkness occurs. Having twisted the regulator in the opposite direction, then be prepared who the fact that the light will be turned on even during the day, if you hurt a big cloud.

Here, how is the process of turning off the light when dark: the level of illumination falls, the resistance of photoresistors begins to grow, the voltage based on the transistor grows. When the voltage reaches a certain level, the transistor opens and the current begins through the collector, which activates the relay K1. Contacts relay includes a load. The load connects through the output of Load.

LED lights up to designate the working state. To the relay too often did not switch the sensor, for example, from the oscillating branch of the tree, a condenser is installed on the diagram 47 μF, which smoothes all processes.

More powerful diagram LXP-03 lighting sensor:

She is identical to the first scheme in the article, the differences will list:

1. The power circuit is able to limit the voltage in the phase chain.

2. Here is a diode bridge with filters. The same in the previous scheme, I simply showed it very successfully.

3. Instead of one stabilion, as in the first scheme, there are two consistently. Moreover, the voltage remains the same - + 24V.

4. There is a more powerful relay, with a more powerful current of the coil, respectively. Also, it uses a composite scheme for two complementary transistors.

If you know how the scheme works, it will be easily repaired.

Motion sensors To turn on light street and for rooms, help rationally use resources (50-80% electromation), detecting the presence or movement of objects on the site. Modern technologies bring conveniences to our lives, improve the comfort of our existence. Motion sensors automatically include lamps when a person gets into the control zone. When the object is moving, light lights up automatically. This device is extremely convenient when it is necessary to turn on the light, but at the moment your hands are busy. And if there is no movement for some time (which is specified individually), the lamp goes out. Motion sensor street for lighting how to set up? How does the motion sensor connect? Where can I use motion sensors to turn on light?

Yes, anywhere. More specifically, where a person is not long, that is, in the corridors, on the stairs, storerooms, at the entrance, at the wicket.

The motion sensor is a special device that refers to the category of devices for detection. With the help of the sensors, it records a moving object that falls into its zone of action, transmits the resulting signal to the lamp.

By purchasing a sensor to turn on light, it is necessary to consider its parameters, features:

1. Fitting Position: Instruments for switching on light can be installed on the street, in closed rooms, under sheds. They are mounted and embedded, it is also necessary to take into account the specifics of the fastening, the level of protection of the device.
2. Features of the sensor installation depend on its power. The variety of the device affects its installation conditions.
3. It is necessary to take into account the features of the trigger zone, since only visible areas for control are available to the alarms. The response radius is reduced even due to suspended chandeliers or cornices.
4. Glass is an obstacle for infrared rays.
5. Attention should be paid to the presence of an accurate time of the exact time of turning on or off light. This aspect will be important if large rooms where there is not one sensor, but several devices.
6. It is important to take into account the corners of the device, the radius of perception in these devices varies from 180 to 360 degrees. Sensors with perception of 180 degrees are often installed on the walls, they are triggered at the entrance or output of the object out of the room. Ceiling motion sensors are installed only with a full viewing angle.
7. It is necessary to take into account the interaction of the ranges of active and passive sites - this is relevant for office space or rest room.
8. There are categories of devices that have a function setting on human breathing.

Motion Sensors: Views and Classification

Light sensors are divided into two types: by the class of the alarm and the place where the installation will be made. The devices are divided into external (used for the street) and internal (for premises).

Functions of outdoor devices for switching on light work on the principle of calculating the distance from the device to the object. Perimetral type sensors are calculated on a specific part of the territory. Their use is relevant for large private possessions, extensive receiving zones. Most devices have a ratification range rather wide: from 100 to 500 meters. It should also be borne in mind that some types of specialized devices must match a certain searchlight. It is possible to install a room sensor in any room at home, its main difference from the street analogue is the intolerance to the temperature differences.

These devices are divided into:

1. Ultrasound - their work is based on reflection of ultrasound from it surrounding it. This is the most affordable, simple, durable category of sensors;
2. Microwave - work on the principle of the locator. The radar is configured to a specific range of signals. He catches them and sends the alarm. After the signal is caught, the light automatically turns on. Among the experts it is customary to be the principle of action more practical than ultrasound sensors. However, the cost of such devices is higher;
3. Infrared - their principle of operation is similar to the reaction of the super-sensitive thermometer. Such sensors react to the temperature of the object falling into the zone of their action (for example, 36.6 ° C). It should be borne in mind that these devices are dependent on changes in the temperature of the surrounding space, so it is not recommended to install them in the kitchen zone or entrance doors. These devices are optimally suitable for residential premises, the temperature response range can be adjusted so that they do not work from moving domestic animals.

How to connect a motion sensor

To connect these instruments, some special skills are not required, it suffices to understand the principle of connecting wiring and alarm. For more attractive aesthetic perception, the entire system is hidden in a special distribution package. An appropriate installation instruction is attached to each device, as well as a motion sensor circuit for lighting.

The principle of operation something resembles the process of connecting the contacts in a conventional switch, since they are identical to the acting parameters. There and there in the role of the actuator performs the relay.

Practice is widespread when the switch with a motion sensor is used, it is especially true for residents of private houses. When approaching the gate in the dark time over the entrance, the lamp is turned on, and the sensor is configured in such a way that the person can easily overcome the distance from the gate to the house without any problems.

In cases, if it is necessary that the lamp worked even when there is no movement in the room, the switch is added parallel to the sensor. Thus, when the switch is turned on, the light source will be connected to another chain, bypassing the sensor. At the same time, the device will continue to control the lighting even when the switch is disabled.

Scheme with a switch connected

In some cases, when the area of \u200b\u200bthe room is large, one sensor becomes enough, a diagram of connecting the source of lighting with two instruments is used. To avoid interphasis closure, it is necessary to understand that both signaling devices are connected from one phase.

Connection diagram of the lamp with two sensors

Owners of private houses with a large local area territory often combine the connection of sensors and several powerful searchlights. Since the sensor power is approximately 500-700 W, then in such cases a magnetic starter is used.

Motion sensor connection circuit with magnetic starter

How to set up a motion sensor to turn on the light with your own hands

Potentiometers correspond to the sensor setting. They are divided into three categories:

• time intervals;
• sensitivity level;
• illumination.

Setting time intervals is the most simple. You only need to set the required time interval. Depending on the instrument model, this value varies from 5 seconds to 10 minutes.

The higher the level of sensitivity - the better the device reacts to movement. If there is too frequent sensor triggering, the sensitivity threshold should be reduced. This factor also applies to spontaneous inclusions. Setting the level of sensitivity also need to be taken into account the time of year, for example, in summer, the instruments are functioning in standard mode, and in winter there are failures. This situation is formed due to the response of heat to heat produced by heating devices.

The illumination factor is important: the sensor must function correctly when light. Thus, when the object moves, the device must automatically determine the level of illumination. If the level is lower than the installed threshold, the device is triggered. And if there is no higher, since the room does not need additional lighting, on the street day.

conclusions

Movement sensors for switching on light street and home compacts, economical in terms of energy consumption, easy to install them. They are comfortable, relevant for use in private houses, in dachas, in the near-obedomic territories. In addition to its direct destination, they perform a function of a kind of signaling from intruders, it is when other people people appear on your territory.

Motion sensor is the necessary attribute of the modern interior, the functional comfort of your home.
