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.
