question: Microwave Motion Sensor SKU: CQRSENWB01 #87

I would love to use a Microwave Motion Sensor instead of PIR for a higher sensibility and since I could hide it behind the wooden frame.

I tried to use the one from CQ Robot. They provide some information on their wiki page: http://www.cqrobot.wiki/index.php/10.525GHz_Doppler_Effect_Microwave_Motion_Sensor_SKU:_CQRSENWB01[http://www.cqrobot.wiki/index.php/10.525GHz_Doppler_Effect_Microwave_Motion_Sensor_SKU:_CQRSENWB01](http://www.cqrobot.wiki/index.php/10.525GHz_Doppler_Effect_Microwave_Motion_Sensor_SKU:_CQRSENWB01)

I followed the instruction here in the project wiki. And according to the LED on the sensor motions are detected reliably. It connects to 5v, GND and GPIO 21 - which I set in the motion_detector.conf accordingly. In the debug mode I get

INFO: PIR Sensor: Start
INFO: PIR Sensor: Motion detected

each time the LED on the sensor lights up.

I tried it with INTERNAL_RESISTOR=off and INTERNAL_RESISTOR=on since I am not 100% sure which is suitable for this sensor.

However it never is switching to No Motion detected and then turning off the display after the set delay. This is only working as soon as I completely remove the sensor from the GPIO pin.

Is there a way to get this sensor running? I would really appreciate if someone could give me a hint what I am missing here.
