Grove - Adjustable PIR Motion Sensor

Grove - Adjustable PIR Motion Sensor is an easy to use Passive Infrared motion sensor, which can detect infrared object motion up to 3 meters. Any infrared object moves in its detecting range, the sensor outputs HIGH on its SIG pin. And you can adjust the SIG HIGH time up to 130s via the potentiometer, moreover, you can adjust the detection range via the other potentiometer. It will be a prefect motion sensor for your Arduino / Raspberry Pi project.
