How do I make a system where it sends me an alert when a wire is cut?
However, because it's so remote from where we are generally (it's on top of a hill next to us), I need some kind of remote alert system so that I know if the barbed wire has been cut.
I saw a garage door monitor instructable using the parallax "Basic Stamp II" that I think I could modify for this purpose, but I figured this has been done before and their is probably a better way to do it.
I thought of several ways to detect that the wire was cut, like running a small current through it so that when the circuit is broken, it sends the alert (e-mail or something like that), but I don't know how to implement that.
It should be noted that the barbed wire is going to be on top of a 4 ft x 4ft building. There are no gates involved and it is a continuous wire (total 16ft long). I need to have a system that will tell me if any of the four sides gets cut.
I've included a basic layout to help visualize what I'm talking about.
Thanks for the help everyone. This is an awesome website.
