Regular price $6.00 Sale

The PIR sensor is a pyroelectric infrared sensor that can detect infrared rays sent from moving human body or animals. It can output switch signals and be used in various occasions that need to detect moving human body.

*Compatible with the DIY and mCookie series.

Introduction of Pins

PIR Sensor
General Pin Out Sensor / Trinket's Pin Out
PIN1 (GND) GND
