Me PIR Motion Sensor is a module to detect the infrared radiation emitted from human or animal body, and its maximum induction range is 6m. If somebody is moving in the range, its DO pin will output an effective signal to light on the blue LED on the board.

[modifier] Spécifications techniques

  • Operating voltage: 5V DC
  • Output voltage: 5 V/high level, 0 V/low level
  • Trigger signal: 5 V/high level
  • Retention time: 2 second
  • Detection angle: 120°
  • Distance detected: max. 6 m
  • Dimension: 51 x 24 x 18 mm (L x W x H)
  • Connecting with RJ25

[modifier] Programmation Arduino

This is a routine to identify if there is anyone or anything moving nearby. Me Pir Motion Sensor-Arduino.png

[modifier] Programmation Scratch

If the detected result from the module is nobody is moving, the panda will say “Nobody is playing with me!” Otherwise, the panda will say “Somebody is playing with me!” The running result is as follows: Me Pir Motion Sensor-Scratch.png
