Basement Lights Automation Help Needed

Oh, and one more note on placement…

All of these PIR motion sensors work on the same principle, which is measuring a change in heat as it moves across the Detection field. For this reason you will get the quickest and most reliable detection if you don’t place the sensor so that the person is walking straight towards it. Instead you want to catch them moving across the field. For this reason some people place them on the ceiling pointing down, others place them on the wall crosswise to where the people will walk. There are some sensors specifically designed for ceiling mounts which have a wider angle to catch people coming from both directions. I would definitely consider having at least one ceiling mount sensor over the area where the kids will be playing.
