Has anyone tried to interface an arduino with one of these sensors?
It is a replacement sensor for home security lights. It is capable of sensing motion 70 feet away (21 meters).
Here's all I know: -the lighting system runs on 120 v ac but I'm not sure if that much power goes into the sensor, maybe just the lights. -There are three wires: Black(power) White(Ground) and Red(for turning the lights on)
If I hook the Black to 5v and White to ground, and Red to Analog 1, all I get is a number in the 1020's that jumps around.
It is sold here: http://www.lowes.com/pd_247582-85538-SH-5316-BZ_4294857027+4294882837+5003700+5003720_42949370 but there is no information there except for a picture.
