Mini PIR Mosion Sensor v1.0

Products & Technology
#1

Hi there,

I got a mini PIR motion sensor v1.0 (https://www.seeedstudio.com/Grove-mini-PIR-motion-sensor-p-2930.html) 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

Thanks,
Yevgeniy
