How to connect a motion sensor to a light bulb. Motion sensor connection: circuit

Today, few people can be surprised by various innovations used in the arrangement of living quarters. For quite a long time, the use of such a device has been practiced, which is responsible for switching on and off the lighting when a person enters the room. Despite the seeming complexity of such equipment, almost everyone can produce it themselves, for this you only need to know all the nuances of this work and carefully follow all the recommendations for installation.

Therefore, it is necessary to consider in more detail how to correctly install and connect the motion sensor for lighting, as well as to understand the design features of such a device.

The scope of motion sensors

If earlier to buy this device it was possible only for very big money, then today almost everyone can afford to have such equipment at home.

Its installation is carried out, as a rule, in the entrances of residential houses, in private structures, as well as in various enterprises, which provides additional comfort and security for people.

The main purpose of the motion sensor is to turn on the lighting device when a person appears. In this case, the automation is activated, which is responsible for the activation of the entire system. Moreover, such a mechanism can respond not only for the inclusion of light, but also for sound, signaling, etc. But then we will discuss how to connect a motion sensor to a light bulb. This is primarily due to the fact that this version of the device has become the most widespread among the population.

Technical design features

Externally , the motion sensor for lighting has the appearance of a small plastic box having a rectangular or circular shape. The device is also equipped with a small diameter hole, closed with a matte film. This plastic partition is called the Fresnel lens, and it is on its properties that the principle of sensor operation is based. Handle it carefully, so as not to damage its integrity and not to disrupt the process of the entire system.

Tracking of motion becomes possible also thanks to the infrared ray beam located inside. In addition, the body is also equipped with special hinge legs, thanks to which it is possible to change the position of the device.

The sensor can be fixed either on the wall or with a special auxiliary bracket. Sometimes the body can have an on / off button, but there are samples without it, it all depends on the specific model and type of equipment used.

Types of motion sensors for lighting

In order to understand how to install a motion sensor, it is necessary not only to study the information on its installation, but also to select the desired sample, since there are several categories of such equipment. So, there is a separation of these mechanisms in accordance with the place of installation and according to the type of signaling device, but the two largest groups are sensors for the street, or outdoor, and for indoor (internal).

The working principle of the samples for the street is based on calculating the distance from the device to the object. This option will be convenient for private houses with a large territory, as well as massive structures of administrative and economic nature. Some models for high-quality work require a spotlight, which is important to consider when installing.

The room sensor can be connected to any of the rooms, however, when using it is important to ensure that the microclimate is more or less stable, that is, without sudden changes in temperature, otherwise the device may simply fail.

In addition, this equipment can be divided into the following categories:

• Ultrasonic motion sensors for lighting. They function by reflection from the surrounding objects of ultrasound. This option is affordable, it is durable and easy to operate.
• Infrared devices. The principle of their action is based on the sensitivity to temperature changes. This means that when the wave hits a radius with a certain heat index, the light comes on automatically, and the desired parameter can always be set so that the mechanism does not work, for example, when an animal appears.
• A microwave sensor, identical in its operation to a standard locator. The device periodically transmits signals having a certain frequency, as a result of which after the capture of the device is turned on. Such samples have some similarity with ultrasonic devices, but their cost is higher.

Advantages and disadvantages of equipment

In order to understand how to correctly connect a motion sensor to control light, you certainly need to study all the positive and negative sides of such a device. And already on the basis of these data, to conclude whether it is worth it to install or not.

The merits of this popular and convenient mechanism are the following:

1. Low consumption of electrical energy. Thanks to this sensor, you can not be afraid to forget about the need to turn off the light under any circumstances, since such a problem is solved automatically.
2. Comfort of operation. The use of this equipment will avoid long searches for the switch in the dark.
3. High level of functionality. These devices are quite able to do without wires, which makes their use more convenient.

However, such equipment has two main drawbacks:

1. The high price, as a result of which its installation can not afford all.
2. Relatively complex installation process. The most important elements when deciding how to connect a motion sensor are the instructions and the diagram. Installation provides for certain skills to work with such equipment, otherwise it will be more appropriate to seek help from specialists.

How to determine the location for mounting the device?

Before connecting the motion sensor to the light bulb, it is necessary to carefully approach the choice of its mounting location, which must be calculated in such a way that the device always works and does not react to foreign actions. It is necessary to secure the mechanism from external interference and ensure its normal operation both from the network and permanently.

It is extremely important to remember here that it is not possible to install a sensor near the central heating radiators, close to air conditioners and electromagnetic devices.

If the equipment is connected in the wrong place, it can react even to minor fluctuations such as rocking trees or moving around the perimeter of the house. Therefore, it is necessary to choose a suitable site where no thermal or other effects will be applied to the device, and there will be no foreign objects within its coverage zone that can affect its operation.

Adjust motion sensor for lighting

Any technical equipment used in everyday life, as is known, requires preliminary tuning. Therefore, when a question arises as to how to install a motion sensor, it is necessary first to adjust its mechanism so that it works as accurately as possible.

Usually, these devices are connected directly to the electricity network with a standard voltage of 220 V. This should not be done only with radio models whose operation is based on the use of a battery.

In order to facilitate the master such a procedure as the connection of the motion sensor, the circuit for its installation is usually displayed directly on the surface of the device in the vicinity of the terminal block.

So, to test whether the equipment functions, you can pay attention to its indicator. If it is on, there is nothing to worry about, but if not, you should set up the device differently. As a rule, a certain role is played not only by blinking itself, but also by its frequency, which increases when a person appears in the zone of its range.

The housing of any of the devices is usually equipped with special adjustment knobs, thanks to which it is much easier to adjust the operation so that electricity is consumed in a minimum amount in the day, there is an opportunity to adjust the range of sensor coverage and so on.

Tools for hand-assembled motion sensor

Such a device, if desired, can be designed and hand-made. This will require the following set of tools:

• One-piece case (the base from the old camera will do);
• Base of control of element type (it is possible to get in specialized shops);
• Screws;
• Wires;
• Soldering device;
• screwdriver.

Further, all the functional parts of the future sensor are required to be assembled, while many owners have a question: "What is the optimal connection for the motion sensor?" In order to design and connect the device without any unnecessary problems, it is necessary to take into account the features of the device, its technical characteristics and, of course, the correct connection algorithm. Therefore, it is necessary to understand in more detail what these installation instructions represent.

Scheme of device mounting

When performing a procedure such as connecting a motion sensor, the circuit involves pulling three wires from the distributor box to the device - this is the phase, zero and the third contact from the twist of the switch with the lamp. In this case, it is possible to short-circuit the mechanism so that the light is turned on forcibly and for a long time, even if there is no movement. This will be convenient, for example, when working in a garage, when very little is done while repairing a car. This can be achieved even though virtually all instruments of this type are equipped with the ability to regulate the duration of the lamp after receiving a signal about the movement that has occurred in the sensor's coverage area. Typically, the terminal board of the device has several notations, the main ones of which are L (phase), A (lamp), N (zero).

Motion sensor connection for lighting

When deciding how to connect a motion sensor to a light bulb, the following installation rules should be taken into account.

The device is connected in a chain between the luminaire and the switch by mounting two wires that disconnect both these parts from each other. This means that the device will be located between them. As a result, the lighting element will function both from the sensor and from the switch.

It also happens that it becomes necessary to install several such mechanisms in a row, for example, in a warehouse. The circuit of their arrangement is similar, but in this case the wires should be placed around each of the lamps separately. Alternatively, the main wire can go in a circle from the switch, while the lamps will be connected to it by a chain. In this case, the sensors are mounted both between the input wires and at the output of each light.

To make the installation as safe as possible, the room should be de-energized beforehand, the wiring must be cut in the places where the sensor wires are connected, which in turn must be cleaned and twisted together. At the end of the work, it is important not to forget to carefully wrap each of them with an insulating tape.

Recommendations for mounting motion sensors

It is important to remember that the installation of any of these devices requires an individual approach, since the connection instruction may be different, but the main thing here is to equip the device in a place where foreign signals do not affect its operation.

When discussing the topic: "How to connect the motion sensor (turning on the light) yourself", the following tips should be taken into account:

1. For mechanisms with wires, the installation site should be carefully selected, since such devices should not often be moved from one location to another.
2. It is more correct to mount an additional switch, while both devices can operate separately from each other. This will dampen the light in a standard way.
3. Premises with a design design is best equipped with a built-in alarm that perfectly fits in the interior.
4. Before acquiring a sensor, you should ask the consultant for help with the question of what range the device should have in a particular room. A good solution is to connect the ceiling mechanism, almost invisible to the eye.
5. It is important to prevent direct sunlight from reaching the instrument, otherwise the device may soon fail.

Following all these recommendations, you can save yourself from many difficulties. That's all. Now you know how to connect the motion sensor to the light bulb. And this knowledge will help you competently make the installation and provide the equipment with high-quality work for a long time.
