GSM based home devices control system

The project aims at a system allowing user to control home based appliances through Sms along with acknowledgements. Here user need not switch home appliances on and off manually.
Our system allows user to operate these devices through sms, also the status weather the device is switched on or not is sent to user via a return sms. This can be used by domestic users and company users to operate as well as check status of home and company appliances from anywhere in the world.
It is a very convenient system for users since it allows them to easily control and monitor these appliances from anywhere. An example is that a person may switch on his House or office AC 15 minutes before he arrives so that he gets a cool environment as soon as he reaches there.
