Hi guys,
I'm planning to make a gate sensor for some friends and whilst I have an EE background I haven't done any circuit design since university, so I thought I'd pick your minds here.
It is a pretty basic setup. Their house is quite a distance from their front gate, and they have a dog so it has two purposes: the first is letting them know when the gate is being opened, and the second is knowing whether it has been left open or not. (The dog got out last w/e and got hit by a car, fortunately it is ok though).
The basic design was to include a volume controlled bell/chime to indicate when the the gate was opened, and a LED to indicate if it was either open or closed. An additional option would be to have a optional alarm to ring when the gate has been left open, and an override button to turn this off.
Any suggestions would be much appreciated!
Thanks in advance,
