I installed this on an outside 120V light fixture and it works well. The light stays off during the day and only turns on at night when it detects movement (from heat-emitting bodies, such as people). Seems to me that this should eliminate triggering the light from things like blowing leaves, unlike the radio frequency sensors. Note that it needs direct-line-of-sight to work. It does not work through glass or anything else. The light will turn on from about 20 feet away. Directions say 40W maximum load.
The sensor works. Won't deny that. But I'm going to have to get a different one that will allow it to function with daylight coming in. This one MUST be shaded or in a dark setting to function. I docked a star because I saw no mention of this in the ad.Installation was easy enough. The included wiring is TINY though, you definitely don't want much of a load on it at all. So much so that I went with a Solid State Relay being activated by this switch to kick on the fridge lighting even though it's only pulling a measured 37 watts.All in all not a bad piece. Small and inconspicuous, functional with unmentioned limitations.
