      Hi everyone!
      I’ve got a doubt. I’ve been watching a few videos on youtube on how to connect the pir sensor to the raspi.
      In every video, they use an arduino or a protoboard. Is this really necesary, or with the female-female cable, the PIR sensor and the raspi is enought?

      Kind regards

        Hi,

        you do not need to use an arduino or anything else. Just connect the Pir-Sensor to the raspberry pi like this:

          I have it wired a little different. I have it connected to a different GPIO Pin.

          Following this guide worked beautifully.

              @PtrBld Hi! I am trying yo use the PIR-Sensor module, but I have no result, the screen never goes black.
              I have connected the cables as the picture you post. Any idea why is not working?

                Maybe you should calibrate your PIR sensor tuning. There are two little orange knobs where you can adjust the sensitivity of the sensor.

                  @pepemujica Good way to make sure you have it connected correctly and that the PIR is operating is to try out the python code in the link I sent.

                  from gpiozero import MotionSensor
                  
                  pir = MotionSensor(4)
                  while True:
                      if pir.motion_detected:
                          print("Motion detected!")
                  

                  Keeping in mind for both this code and the module that you have the correct pin number.

                    How do I know in what pin are the 3 cables connected?

                      You have 5v, Ground, then GPIO.

                        @McSorley so, the (4) you’ve put in the example before, wich of the 3 cables is?
                        Sorry, I’m pretty new in this, and I can’t get it easyly
