Why does my motion sensor stay on when it is dark?
Some times it is the wind that sets them off. I have trees that are close to the house that the sensor is pointed directly at. When the wind blows they trip the motion detector. If the sensitivity is turned up to the top it will pick up small animals. To set this sensitivity do a walk test at night. Get someone to walk past as you turn the sensitivity down. When the sensitivity is down so as not to pick the subject up give it a 1/4 turn to the plus side and that should stop needless tripping.
