I have PIR Motion Sensor with old GrovePi, see photos on http://imgur.com/a/pEUt7.
When I run grove_pir_motion_sensor.py sample script it prints “Motion Detected” few times and then “-” few times. Those values are flapping all the time every ~0.5-1.3 sec. I tried putting a sensor towards a wall or waving for longer time, but output doesn’t change.
Do you have any idea why the sensor doesn’t recognize motion properly?
P.S. I’m attaching output from grove_pir_motion_sensor.py script and troubleshooting logs.txt with hardware info.
