Home Assistant: Use a Motion Sensor to Automatically Control Lights

Motion Sensor Hardware and Calibration

  • VIN: The PIR works with either 3.3V or 5V, I recommend using 5 volts
  • GND: Connect to ground
  • DATA: The data pin is binary, and therefore needs to be connected to any input digital pin of your board
  • Time delay: determines how long the sensor sends an active high after detecting a movement, in its clockwise lowest settings, that’s about 1 second, and in the highest, about 4 minutes
  • Movement sensitivity: Controls the measurement distance from about 1,5m — 6m
  • Position H: In this position, the sensor will send an active high signal for the complete time delay setting, and in
  • Position L: When movement is detected, the sensor will send an active high followed by active and remain low for the time delay
  • Measurement distance potentiometer to 1 o’clock (lowest distance of 1,5m)
  • Movement duration to 3 o’clock (movements need to persist for 0,5–1 seconds)
  • Set the jumper to H
