Glad to know you have finally your gsm system at work.

- Think more about the real case scenario, because at first stage I would like to use this as an alarm system for my garden house. I will need some sensors for unexpected visitors or animals.

Do you have any idea, what kind of sensors I can use to detect unexpected visitors?
Just take a look at one of my project @ http://techni.caliti.es/blog/2008/12...ontroller.html
