i want to know if there is a way to take an ac motion switch and make it so it works with dc power so that i can have it activate a relay instead of a light

What model is the AC motion switch?

steveharrmr23 · 28th August 2009, 06:42 PM

it is maid by cooper i pulled the chip and everything out of it

if that helps

Got any part numbers or model numbers? Based on what you are giving us it is very hard to come up with an answer!

Why not use an AC relay?

steveharrmr23 · 28th August 2009, 09:27 PM

cause i am putting it in a car and it is dc not ac

What voltage is it on AC?

They usually use a capacitive reactance supply (ie a capacitor) to provide the few mA DC supply required by the PIR motion sensor.

It should be fairly trivial to convert it to 12v DC use.
