I don't know about a GSM relay, but two companies that I know of sell GSM modules that can be interfaced to a microcontroller. The companies are http://www.sparkfun.com and http://www.adafruit.com. They look interesting, but I can't program my way out of a wet paper bag, so I'm impressed by anything that can make a few lights flash.

I don't understand how these work. Do you have to add them to your cell phone contract and pay a monthly fee for them? It seems like a huge expense

I would get a GSM shield and use text messages to control the gate. I'd consider getting a T Mobile sim and put it on the free 200 megs a month plan.
lots of sketches out there for SMS parsing on an arduino. one of these and pretty much any arduino. |
