I like the angled sensor idea also. As for my delayed sensor, I actually had
two sensors and both had to be cleared, I figured the odds of two gaps over
the sensors would be pretty rare. Do note that my sensors were (are) Radio
Shack light sensors between the rails using the room light as a source, so
they are pointing straight up.
