The main goal of this project is to develop a device that controls the home appliances through SMS with incorporated acknowledgment feature. Unlike the conventional framework introduce in houses, where one needs to manually switch on and off the appliances.
The proposed framework enables the proprietor of the house to control the applainces by simply sending an SMS to the device and after that likewise getting the status of the same through return SMS.
This is extremely convient for clients as they can control their home loads anytime and anywhere on the world . A case of how this technology can improve our lives is that when a man is travelling and wishes that the minute he goes into his room, it ought to be sufficiently cool to make him comfortable.
In such a case, with the assistance of this framework, he can switch on the AC while he is voyaging. An SMS is sent to the GSM modem which is interfaced to the microcontroller. The modem gets the message and sends the commmand to the microcontroller which forms this and starts a system that initiates a relay to control the comparing home applainces.
An added feature of this framework is that the proprietor can get the status of the loads (whether on or off) in the house by sending a status querry SMS to the base station. All the status can likewise be seen on a LCD display interfaced to the microcontroller.
