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
PIN3 (SIGNAL-A) Digital Input
PIN4 (SIGNAL-B) Not Connected
  • General Pin Out is the standard pin out of a Sensor / Trinket connector.
  • Sensor / Trinket's Pin Out is this specific Sensor / Trinket's wiring in relation to the General Pin Out.
  • SIGNAL-A / SIGNAL-B are signals that could be digital input, digital output, analog input or analog output. Or special signals such as serial communication (SoftwareSerial, IIC (I2C), etc) or other special signals.
  • Not Connected refers to the Pin not being used for this particular Sensor / Trinket.
