Hi All
I'm trying to come up with a way to detect if someone is coming up the pathway to the house (say when they get halfway)
My pathway from the front door to sidewalk is only about 15 feet, so I don't think a PIR-type sensor would work
The only option I can think of is to use some kind of beam that would get broken, but I don't want to dig up the yard to run wires or have things sticking out the ground.
The only thing I can come up with is to attach a transmitter to the wall of the house and point it diagonally to a reflector so that it detects someone half way up the path.
Anyone got any other ideas?
Regards
Mark
