Wiring and configuring the PIR motion sensor

Now we connect the motion sensor and write the program in Python language that will establish the sensor's behaviour:

  • Connect the sensor terminals to the following GPIO pins

    motion sensor

    Raspberry Pi GPIO

    Power

    Pin 2

    Signal

    Pin 11

    GND

    Pin 6



    The general diagram (including the LED connection made previously) is connected as follows:

  • We will add the necessary lines to read the PIR motion sensor’s output to the program written in Python language. The sensor outputs a HIGH (5V) digital signal when detecting a person or animal’s presence.
