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

  • Pins of the sensor:
    • PIN1: GND
    • PIN2: VCC
    • General signal pins:
      • PIN3(IO1): digital/analog signal
      • PIN4(IO2): NC(null)
    • Special signal pins:
      • If it is IIC: IO1/IO2 are respectively SDA/SCL.
      • If it is soft serial port: IO1/IO2 are respectively tx/rx.
  • Special to Sensor-PIR sensor pins
    • PIN1: GND
    • PIN2: VCC
    • PIN3(IO1): Digital read
    • PIN4(IO2): NC


Microduino sensor can communicate with core module through the connection with Microduino-Module Sensor Hub.
