Electronic occupancy sensors have several uses, including improving home and office security and helping reduce energy use, especially lighting, in unoccupied spaces. Occupancy sensors generally combine a motion detector with a timer and electronic light switch to turn on and off lights when they are not needed. For security, they can be linked to an alarm.

Types of Occupancy Sensors
We stock two types of motion detectors: passive infrared (PIR), and microwave emitters
Passive Infrared (PIR) Detector
PIR detectors, the simplest type, have a sensor face that measures different air temperatures in a room. PIR detectors are considered passive because they do not emit any light, sound or heat. Computerized sensors inside the detector compare the average room temperature with the increase in heat that occurs when a human walks past the sensor. The PIR detector sends a signal to switch on lights when a person is in the room. Once the room temperature returns to its average value, a signal goes to the light controls to turn the lights off.
