PIR Sensor turning display on/off over and over
-
I have the same issue. Maybe it’s related to WiFi. I tested the PIR with on older PI 2, no WiFi. Ran the Python script, working perfectly.
After installing the PIR to my Mirror Pi, a Pi 3 screen wouldn’t go out. Installed the test Python script again and I am getting a lot of false positives, over 5 a minute. So PIR stays highs and screen stays on.
I am thinking that WiFi is interfering with the PIR.
Anybody any experiences or ideas?Thanks,

by my mirror it works really nice. i have a question, it is possible the time to change right now it turns the display off after 4 minutes. i would like to change the time maybe 2 minutes or so.
thanks

It might be interference. Try installing a ferrite bead. The person whose site I’ve linked below had a very similar problem and describes how he fixed it.

It’s what I had to do with mine… they are very inexpensive…

Thanks @Renfield and @cowboysdude ! Followed your advice and found a ferrite bead on unused USB cable and got the PIR sensor working perfectly!

Great to hear. I love it when a plan comes together.
Now I need to scrounge up a bead for my build.

Hi all,
Thanks for the reactions. I ordered one and will test tomorrow.

i gave up on my PIR sensor cause this was happening to me…guess who is searching for a Ferrite bead tomorrow!!!
