Abstract

An embedded project is a combination of hardware and software, designed to perform a specific task. In embedded technology the embedded programming is burnt into the AT8C52 micro controller. The main scope of the project is mainly based on the advertising of applications using RF modules.

In this project two Radio Frequency modules are used, a transmitter module and receiver module. The transmitter Module consists of switches, encoder, RF Transmitter and PC. PC is connected to transmitter module which transmits the characters to the receiver module. At the other end the receiver consists of micro controller, decoder, RF receiver, and an LCD which receives data from the transmitter module and displays it on the LCD. The control operation of the system is done with the help of PC.

Radio Frequency (RF) is a frequency or rate of oscillation within the range of about 3 Hz to 300 GHz. In this project we are using a 433 MHz frequency RF module; this is a license free frequency so we can use it without owning a license. The range of this frequency can be up to 12 Km.
