Embedded Based Secured Wireless Data Communication

Abstract

This project is developed for the users to send and receive information through Microcontroller in a secured manner. It mainly consists of two units called sender and receiver. The sender unit consists of a microcontroller, driver, RF transmitter and LCD display. The Receiver unit consists of a microcontroller, driver, RF receiver and a LCD display. The data is stored in the first microcontroller. The microcontroller sends corresponding signal to the driver unit and the driver unit operates a RF transmitter. Thus the RF transmitter transmits RF signal accordingly with the data. The RF receiver connected with the receiving unit receives the signal and sends to the driver section. The driver section drives the signal and sends to the microcontroller. The microcontroller sends corresponding signal to a LCD display. The message is displayed in the LCD display. Thus one can easily send and receive data from one Microcontroller to other. The microcontroller program is written in assembly language.
