I'd like to hook up a remote sensor at end of my driveway to alert when someone arrives.
It's very far away from the house; about 500ft or 150m, so naturally I don't want to run a cable out there.
Second option would be to use a RF transmitter but they can be prone to interference and it'd have to be adequately powered at that distance.
Third option, I thought of was using home automation technology like X10, Insteon or similar that I believe communicates over power lines. I don't know if that'd be feasible at that distance.
Oh, did I mention that I have a 120v circuit that's already out there for lighting?
I've heard of power line communication (plc) where a microprocessor or computer can send data over power lines but don't know much about it and dont really need the bandwidth.
Since I really only need one bit of data (on/off) to trigger a chime at the house, would it be feasible to use some kind of oscillator circuit to send a frequency and superimpose it on my household 120v 60hz circuit, then monitor that frequency back at the house?
Thanks in advance for advice and guidance.
