This Grove – PIR Motion Sensor(Passive Infrared Sensor) can detect infrared signal caused by motion. If the PIR sensor notices the infrared energy, the motion detector is triggered and the sensor outputs HIGH on its SIG pin. The detecting range and response speed can be adjusted by 2 potentiometers soldered on its circuit board, The response speed is from 0.3s – 25s, and max 6 meters of detecting range.
The Grove – PIR Motion Sensor(Passive Infrared Sensor) is an easy-to-use motion sensor with Grove compatible interface. Simply connecting it to Base Shield and programming it, it can be used as a suitable motion detector for Arduino projects. For example, the PIR Motion Sensor are commonly used in security alarm systems and automatic lighting applications.
