List of featured suppliers of LIGHTS: OTHER PIR Passive Infrared Presence Detectors on Building Products Index
Lights that incorporate other types of sensors such as PIR (passive infrared) and presence detectors are designed to detect the presence of people or movements within their vicinity and trigger the lights to turn on or off accordingly. PIR sensors detect the infrared energy emitted by all objects and people and can sense when there is a change in these emissions. Presence detectors, on the other hand, use various technologies like ultrasonic, microwave, or infrared sensors to detect the presence of people in a room. These sensors are used for convenience, energy efficiency, and security in various settings like residential, commercial, and industrial buildings.
