I'm not sure if I know how to ask this correctly.... but here goes.
Can anyone tell me if motion sensors are more or less all the same voltage wise or do they match the devices they control?
What I mean is... if the sensor is triggering a standard 120v light fixture, does that mean that the sensor itself is a 120v device? Or am I thinking of it all wrong?
I'm curious to know if a sensor for a low voltage DC lighting system is different than one for AC... and even further would the sensor for a 6V system be different than one for a 12V system?
I've seen some motion sensors that require a 9V battery and others that do not and I'm not sure how that figures in.
I hope the question makes sense.
