Mini PIR Mosion Sensor v1.0

Hi there,

I got a mini PIR motion sensor v1.0 ( for some experiments. I connected it to a 3.3V supply and monitor the “REL” pin with a multimeter.

  1. The sensor trully consumes < 200uA
  2. The “REL” goes HIGH once the sensor detects an object, but it stays HIGH until the next power cycle.

I assume the ON time delay needs to be adjusted, but I did not find a clear direction on how to do that. Any help would be appreciated
