The other sensor I'm testing is from Amazon.
SensorPlug - Motion Activated Electrical Outlet - Amazon.com
I have it controlling the single tube florescent light above the kitchen sink.
I've taped over about 70% of the sensor dome. I want it to turn on the light,
only when someone stands at the sink (left of the microwave). It's kinda working.
In a week or two, we'll know if we have a good setup, or not.
