Thread: IR object detection
face BY : Jim email (remove spam text)

I bought a Radio Shack Infrared Alarm unit a
few years ago - it's pre-built and has a relay
contact as output - and it works on my porch
(not direct sun, but indirect sunlight).

Comprised of a combo Sender/Rcvr and a special
"mirror" placed several to five feet away.

Break the beam and a contact closure occurs.

Size: about 8 x 6 x 4 inches.

More info if interested ...
