Choosing a motion sensor to illuminate correctly

The use of motion sensors in lighting not only saves electricity (which is constantly increasing price), but also to make use lighting more comfortable and even improve the security of your home (including a sudden light can scare off potential robbers). In this article we consider the basic criteria that should be selected in motion sensor.

The main selection criteria

There are a number of rules, following which you will be able to choose the correct motion sensor for your particular room. So, let us proceed to consider these rules:

1. In advance to determine the place of installation.

From where you plan to install the motion detector directly the degree of protection depends on the product's enclosure. For outdoor installation is best suited detector with protection IP 65And the minimum allowable level is IP 55.

If you plan to install the device under the awning or canopy, then let's figure of IP 44. And to be installed inside the heated space with a low dust content and moisture can be installed even products with a lower degree of protection.

2. Choosing sensors according to the presence of obstacles.

As is known, there are several types of motion sensors:

- infrared. They react to the infrared radiation (heat) coming from humans, animals, and various objects.

- Acoustic (sound). Such sensors are activated in the presence of a sharp sound, it does not matter who or what was the source.

- Microwave motion detectors. Such articles have a built-wave emitter with which sensor detects even small obstacles.

- combined products. Such motion sensors typically comprise a combination of several methods of motion detection.

So for home use best suited IR - sensors or combined combined infrared and ultrasound.

For use in security systems, warehouses, security system, it is best to apply microwave motion detectors.

3. viewing angle.

It is also an important criterion is to cover the sensor area. If the room has multiple inputs, then the best choice would be a ceiling-type sensor, which wrap angle is 360 degrees. And if the input is one, it is possible to use the product with an angle of 180 degrees. Simply position it so that it is controlled entry to the premises.

4. Switching capacity.

Since the inclusion of lighting in most cases there is through a motion sensor, it is very important to him Power was at least 20% more than the total power of lighting, that is, choose a product with a margin of power.

5. Radius of action.

In most cases, the motion sensors are available on the actuation range from 6 to 50 meters. And if for an ordinary room quite descend the smallest radius, here to activate lighting in an open area need to clearly know the required operation range.

6. The presence of built-in light barrier.

It is best to acquire sensor with integrated light barrier that blocks the light switch when the light level above a predetermined setpoint. This will further save on lighting.

7. Protection of animals.

Pets are active not only in the daytime, but at night, so also should pay attention to this function in the sensor, as a defense against animals. This feature allows you to check out from the presence of a pet in the room and react to the appearance of only human. Just keep in mind this is an important factor that microwave sensors may adversely affect the animals.

These are all the main points that should be considered when choosing the motion sensor.

conclusions

Based on the above seven points, you can create a list of references to use different sensors in different types of rooms:

House and the apartment is better to use IR sensor with built-in protection from animals.

In the hallways and stairwells are well suited acoustic sensors, which include light even when the door is opened or just from the sound of your footsteps.

The security of the complex is better to use sensors with active transmitters, which are capable of detecting movement even minor obstacles.

That's all I wanted to tell you about the choice of the motion sensor. I hope this article was of interest to you and you appreciate it Like it, because it will help to promote it.
