    thanks for the help, but i doubt its some kind of movement since its exactly every minute. i tried a different room and its the same.

        Can you share your python code? Perhaps there’s something there

          @sdetweil sry about that

          @uros76 i hope thats not the problem

          import RPi.GPIO as GPIO
          import time
          import datetime
          
          switch=11
          
          
          GPIO.setmode(GPIO.BOARD)
          GPIO.setup(switch, GPIO.IN)
          
          
          
          
          try:
              while True:
                  if GPIO.input(switch) == 1:
                      now = datetime.datetime.now()
                      print(now.strftime("%Y-%m-%d %H:%M:%S"), "something")
                      
                  time.sleep(5)
                  
                  
          except KeyboardInterrupt:
              print("Bye Bye")
          finally:
              GPIO.cleanup()
          
          

          thanks for the help

            @Lipax try different gpio pin, like a pin 18 which is a GPIO 5. It’s default set to input function. Don’t forget to adjust the python code, change switch to 18.

            You might check the GPIO 0 (your pin 11) if it is set to input. Use command: raspi-gpio get 0 or raspi-gpio get to check all GPIO’s.

            Also, use a multimeter to measure the voltage coming out from sensor. It should be around 3.3V for few seconds when sensing detected. This way you can monitor if actual detection / voltage is coming from sensor.

              @uros76
              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.

                      @uros76 ty ill maybe try to find another microwave sensor. pir i find really ugly try to stay away from them. really sad i didnt get the microwave sensor working. thanks for the help
