A couple things I've found. 1) Animals will trigger it. 2) Stakes don't come close to holding tolerances well enough to keep alignment. 3) Debouncing the input seems to make it work during most weather. I have holes bored into concrete fence posts, hiding the mirrors/detectors and making things much more stable.
