PIR Sensor turning display on/off over and over

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!!!

FWIW, a ferrite bead is a working solution, but I was able to circumvent this issue by keeping the PIR Sensor a good distance from the Pi. Mine is about 3 feet away from the Pi and doesn’t act erratically as it did when it was right next to it during testing.

Similar problem here, PIR works like a charm (tested with code of post #4) but after starting the MagicMirror the display is turned off and on over and over even though nothing is changed in front of the sensor. (I use MMM-PIR).
