Password Protected GSM Based Device Control projects main idea is to provide a new concept for handling home appliances remotely using GSM technology. MAX232 is the micro controller used for interface GSM Device which works on serial communication. Home appliances which are to be remotely controlled are first connected to interface and it will communicate with micro controller on serial communication. In order to control the devices remotely we need to send a message with set up information using GSM which will store in the program.  Micro controller will perform requested operation like switch ON or OFF device. Two way authentication is available in this application, Replay will be sent to user with the information on which device is activated and that information will be displayed on the LCD screen. This application is not restricted to single device it can work for many devices at same time.

Applications for this are Industries with heavy parameters to handle, complicated areas where we can’t monitor the conditions manually; these are Now-a-days used in all kind of industrial and commercial complexes.
