Wireless secured data transmission kit is used to communicate or transmit a text message from one place to another place through wireless. The text message is encrypted by using the Microcontroller and the encrypted message was transmitted through wireless. At the receiver end the signal was received by the standard receiver and the analog signal was fed to the Microcontroller and it was decrypted by the Microcontroller and the message was displayed over the LCD display. We can use several receivers and the message from the transmitter can be sent to the entire receivers at the same time. Each receiver can be accessed separately by its address.

The Wireless secured data transmission microcontroller is used to do the above work. It gets data from the Keyboard and encrypts with a private algorithm and at the receiver end, the Microcontroller decrypts it with the same algorithm and displays the data over the LCD display. The whole kit is based on the working of encoder-decoder IC pairs, HT12E and HT12D.

These ICs have the capability to encode/decode 4 bits of data and 8 bits of the address. Using these Wireless secured data transmission combinations, we can distinguish the different items uniquely. Each id is made with an RF transmitter and ht12E IC. The receiver keeps on receiving the id of different transmitters if the address of the receiver and transmitter matches. The 4 bit of unique data is decoded and the item is identified from a predefined table made for each message. The corresponding message for each id is displayed on the LCD.
