I have a hall that has a light switch in three different locations. All three will turn lights on or off. I want to put motion sensors in all three locations so the lights won't get left on. Can this be done.

Don't think there is such a thing as a 3-way motion sensor.
Multiple motion sensors can be installed. Can also be installed in conjunction with 3-way switches.
Takes a bit of wiring to get the circuitry right.

Do you need multiple motion sensors?
