Does anyone know if there is a 2 wire exterior rated motion sensor available?
No neutral wire available. 120 volts.
Thanks

Here's One:

I would shop around, (ebay?)
This one doesn't have 2 blacks as mentioned on the other post, functions the same.

An exterior motion detector typically goes at the light. How can there be no neutral?

Are you replacing an exterior switch with it?

I seen this other post about interior motion for light literman questioned, and was still thinking interior:

The interior ones will work with no neutral, they complete the circuit, they won't operate without a load to complete the circuit.
