PIR sensor is an IR sensor to detect human motions. This Grove Digital PIR Sensor is the cheapest PIR sensor in the PIR families, however, it is able to give a quick response and generate a high signal from the “sig” Pin.

With the Grove interface, the Grove digital PIR Sensor is easy to be plugged and played. And it doesn’t need any Arduino Library.


  • Budget-friendly: less than 3 dollars
  • Intuitive: detect motion and output with only ‘high’ and ‘low’ digital signals
  • Simple: no external arduino library required
  • Interface: Grove
