That Ebay sensor came today and didn't work at all..
Energy Saving Motion Sensitive Automatic Light Lamp Sensor Switch AC 180 250V 2 | eBay

I'm getting senile! "AC 180-250V" means it won't work for my 120v lights!!

Edit:
My suspicions confirmed! When I looked at the install info with the new 'Sensor'..
There wasn't one word about Motion Sensing.. Just about turning off and on with daylight..
Which it should do, in addition to Motion Sensing.

There is no way a simple LDR can sense the IR from your body in a dark room!

This device is just for turning lights off during the daylight hours. I've been rooked!

Here's an actual motion sensor chip. (from my garage security system).
