PIR sensor not working after installation

  • Hi everyone !

    I followed the steps of the readme, but after rebooting the screen never turns off.
    I don’t know where I am wrong but it doesn’t work ^^

    Thank you.

  • Is the sensor pin configured properly? Meaning in the config file for the module, the sensor pin defaults to 22. Is that the same one your sensor is connected to?

  • @hartattack I connected the sensor to the pin 22. I didn’t change anything else.

  • UP ! 🙂
    I need help please ^^

  • I test the sensor with this, but it marks indefinitely “motion detected”.

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

    Edit : I connected it to the GPIO 4

  • I’m having the same issue. Should the screensaver be off? I did the original config;

    sudo nano /etc/xdg/lxsession/LXDE/autostart
    add the following lines:
    @xset s noblank
    @xset s off
    @xset -dpms
    sudo nano /etc/lightdm/lightdm.conf
    add the following lines:
    xserver-command=X -s 0 -dpms

    but the screen was still blanking after 10-15 minutes so I installed xscreensaver to get around this. I’ve now taken xscreensaver off, so the screen is blanking after inactivity again, but MM doesn’t seem to recognize the PIR. I get the same results of ‘Motion Detected’ when running a .py test from the OS.
