PIR is a short form for “passive infra-red”, this is a type of motion detector that uses infrared technology to pick up movement by sensing body heat and consumes relatively little energy. Other types of motion detectors available are ultrasonic, microwave, and optical sensor; dual technology motion sensors combin
