PIR sensor not working after installation

hartattack

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.
