      Hello,

      i use A2D and working pretty good. But i have trouble with PIR sensor NC-SR501. I set up PIR and countdown working, but after 10-20s reset countdow to 5 minutes. I try change possition on potenciometer (sensitivity/time) on PIR and same trouble. If i disconnect PIR, coutdown work and after 5 minutes black screen.

      Do you have idea where is problem? Faulty PIR?
      I think that PIR not working correctly, becouse automatically change value, but I do not make any movement in front of the sensor.

      If i try test from wiki A2D PIR, value automatically change 1/0, but I do not make any movement in front of the sensor.

      I tried change value reverse, and no sollution.
      I tried change GPIO on RPI and same problem.

      Thanks.

            @Bugsounet I have problem with PIR becouse value change automatically.

            pi@raspberrypi:~/pir $ node setup
            [PIR] PIR v1.0.4 Initialized…
            [PIR] Start
            [PIR] Sensor read value: 1
            [PIR] Detected presence (value:1)
            [PIR] Sensor read value: 0
            [PIR] Sensor read value: 1
            [PIR] Detected presence (value:1)
            [PIR] Sensor read value: 0
            [PIR] Sensor read value: 1

            This value change automatically. No start with hand etc… PIR faulty?

              @ondrax 2 ways to solve this problem:

              1. decrease the sensibility of the pir sensor
              2. the sensor may be near a heat source (a lot of infrared is emitted), in this case move it in other place [I have personnaly this case, because my pir sensor is above my domestic heating. i move it and works]
