      i forget to mention i already changed the pin, i first tried pin 7 before

      according to pinout.xyz my pin 11 is gpio 17

      GPIO 17: level=0 fsel=0 func=INPUT
      

      thank you very much for helping me, i dont have a multi meter but ill ask my father to do that. u think its not the sensor sending the signal? maybe it picks up something with the wire along the way? i dont have a engineering background.

        @Lipax you need to be sure that sensor is not the cause.
        Measuring it’s sensing, output voltage and duration is a good way of confirming if sensor works ok.

          it took a long time but i tested the voltage, i can upload a video somewhere if u want. the wrong positive and the regular ones look the same for me. it kinda spikes to ~5v and then instantly goes to 3.3 and stabilizes

            @Lipax there you go, nothing wrong with the software code. It’s the PIR sensor giving false positives. Nothing you can really do about that. Perhaps a different brand/quality of PIR sensor if it will help but I doubt.

            As mentioned before, due to exact same problem I gave up on PIR sensor completely and moved to the microwave. This works for me now over 3 years. without false positives.
