When the PIR is detecting the moving persons, it'll output high level in the output pin, which is 5V. And when it detected the PIR signal gone, it'll output low level(0V) after 2.3-3s delay. Therefore, we can according to that to establish a moving person detection project according to that.

Sensor-PIR

The product number of Sensor-PIR is: MSDI51

Sensor-PIR 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.


Introduction of Pins

PIR Sensor
General Pin Out Sensor / Trinket's Pin Out
PIN1 (GND) GND
PIN2 (VCC) VCC
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.
  • Read more about the hub module.
