3. PIR sensor not working after installation

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.

    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.
