WebPIR Passive Infrared Proximity Motion Sensor - Adafruit Industries WebA PIR sensor is a type of motion sensor that detects the presence of a person or object by measuring the infrared radiation emitted by them. When the sensor detects motion, it triggers the light to turn on. This means that the light is only on when it is needed, saving energy and prolonging the life of the battery.
