PIR or Passive Infrared Sensor is used to detect objects in their range.
This is a simple to use PIR(Passive Infrared) motion sensor with Grove compatible interface. Simply connect it to Stem shield and program it, when anyone moves in its detecting range, 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.
Grove compatible interface
Voltage range: 3V–5V
2.0cm x 4.0cm twig module
Detecting angle: 120 degree
Detecting distance: max 6m (3m by default)
Adjustable detecting distance and holding time
