How does the Presence Sensors to Light?

With the high price of energy in the country is always necessary to get save. Lighting is an area where you can easily control your expenses. The rationing of energy can be done through the change in the attitude of the users, seeking not to let lamps switched on unnecessarily and also through the use of position sensors and systems.

This type of equipment helps in energy saving, avoiding useless spending, switching on and off the lamps of an environment automatically. But as these presence sensors operate? In this post we’ll show you the your operation and also its benefits, check out:

Operation of the sensors

The sensors detect the presence of persons by the heat emitted by the movements through infrared.These devices can capture the thermal variation and are calibrated according to the temperature of people (35 to 38 degrees Celsius). When a person enters the environment that has presence sensors, occurs a change in infrared light that triggers an alarm on the equipment, engaging so the lamp.

Some of them may work by emitting microwaves, which detect movement connecting the lamps. Both can monitor an area of up to 6 meters and with an aperture of 120. Generally the time of shutdown after detection of the movement is 1 minute and can be changed.

Installation

Presence sensors are usually installed on the ceiling, close to lamps or chandeliers, but can also be placed on the walls. They can also be used on any type of lamps, incandescent, fluorescent, as: Mercury and LED lamps. Usually are bivolts and can be powered by 127V or 220V voltage.

To perform the installation, the electrical power is turned off. Make sure all connections are tight and insulated and be careful not to exceed the power limit specified by the manufacturer of the equipment.

Once installed, in your first use the sensor will take between 3 and 5 minutes to put out the lamp, because it is the time spent for internal configuration of the equipment. After that will always work according to the set time. The sensors can still be used without any modification on electrical design of a house or a building

Choice of sensor

Always opt for purchasing a trusted brand. These devices are inexpensive, costing between 30 and 60 dollars. However, it is better to invest in those that have greater value and to ensure a good performance. The sensitivity and operation of the sensors varies greatly, so evaluate which is most suitable for each situation, an equipment to a corridor of a building is not the same as installed in the garage.

Benefits

The biggest advantage of these devices is energy saving, as well as to avoid unnecessarily, they also lit lamps help when we forget to turn off the lights “. They can be used to ensure greater security, and can be installed at entrances of houses, gatehouses and garages, so they detect motion light bulbs increasing attention from residents.

Now that you have learned better the functioning of presence sensors, comment below and tell us if you already use or intended use this technology in your home.
