The project mainly focuses on transmission of textual data through air interface by the use of GSM through asynchronous serial communication .The data will be processed by the microcontroller on both ends. The data will be displayed on Lcd only after entering unique pass key. In addition to that address matching is done and data can be received only by the dedicated receiver.
Actually what happens is, sending sms through phone has become very popular and if we can use this sms to control devices and in displaying data. It is possible to receive or decode the sms globally by using gsm , by the any part of world we can control and display data on Lcd board .
In this project we not only send the data but send the data with pass code also. Which enables us to prevent the unauthorized use of Lcd display board and only the person who have pass code can have access to Lcd board . Important feature of thesis is we are using gsm network by which we can control Lcd display board by the any part of globe. If we must have the respected pass code. And the pass code is ok then the correct data is to be displayed on LCD.
