I'm looking for suggestions how I can rig up the following:
I want to be able to attach an RF transmitter to a household AC circuit and have a receiver that I can carry with me that will sound a tone and/or light an LED to indicate when the circuit is energized.
I would like a range of about 200-300 feet. I wouldn't mind buying such a setup if someone made one for a reasonable price but I could not find such an item.
With RF devices being common and inexpensive these days, there has to be a way to rig up something like this fairly cheaply. I'm thinking it would likely involve modifying an existing transmitter/receiver set made for some other purpose as opposed to my building circuitry.
Thank you!
