MICROWAVE SENSOR SEN0521

I am using this sensor, Microwave SEN0521 MOVEMENT sensor, and seems all ok. Only one
problem, when it detects a movement it raises a “1” state on the serial trough the function
in Arduino “val = Sensor.readPresenceDetection();” and this state doesn't go back to “0” after
the configured “latency” time …seems to stack to “1” and waits for a kind of reset ???
Should I issue another command to bring it to “0” again ?
This instruction is running in a loop, continuous….maybe need to place a delay(100) between 2 calls
to the same function ?.
.
Thank you for help !!
Best regards,

Yes, I used this code to make the sensor work, but seems to make one shoot and then stop there….maybe stop and restart sensor ?

Thank you

DAVIDE.COGLIATI If you use the code given here as it is do you still face the same issue? https://wiki.dfrobot.com/SKU_SEN0521_5.8GHz_Microwave_Radar_Module
