With the sparkfun PIR motion sensor, I get massive numbers of false positives. I do not see any way to tune down the sensitivity. My first thought is to catch one, hold a second, and check for another - maybe this will help. But looking at my current logs I think I will start dropping real positives. humph. Is my GPIO timing out on the open collector/interrupt at some point? I kind of doubt it, but who knows. Are these “real” false positives caused by EMI or temperature shift? perhaps my garage door shaking with wind does it, but I kind of doubt it since if I stand there and shake the door with my arm about as hard as I can I do not see the hits.
Any other ideas? Thanks!
