      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,
      Herman

          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.

                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.
