In the kit wireless encrypted data transmission today, we live in an age of wireless revolution where every effort is directed towards getting rid of wires. Removing wires not only makes things easy but also improves speed of operation. This project is used to communicate or transmit a text message from one place to another place through wireless RF medium. The text message entered via keyboard is encoded by microcontroller and the written (encoded) message will be transmitted through wireless.
In the kit wireless encrypted data transmission at the receiver end the signal will be received by the standard receiver and the analog signal was fed to the microcontroller and which will be decoded by the microcontroller and the message will displayed over the LCD display. We can use multiple receivers and multiple messages sent from the transmitter and received at the various receivers at the same time. Receiver can be accessed separately by its address. The micro-controller is used to do the above work. It gets data from the Keyboard and encodes it with a private algorithm and at the receiver end the microcontroller decodes it with the same algorithm and displays the data over the LCD display. At the receiver end there is a button (switch) on pressing which we can get the original data.
In the kit wireless encrypted data transmission the main function is controller via programming that is PS2 protocol, According to the efficient programming done and interfacing if the user types anything on keyboard that will be display on LCD in the transmitter block. The controller checks for this protocol efficiency. As the user press the enter key on the keyboard the data is encrypted as per coding and transmitted to remote location receiver. The receiver receives the data as it is and gives it to the controller which is displayed on the receiver LCD in encrypted form. There is a control switch pressing the encrypted data will be de-encrypted and displayed on the LCD.
