Hi Hemanth,
You can use TWS434 as rf transmitter module and the RWS434 as rf receiver module.
You need two 89C52 microcontrollers, one at transmitting board and other at the receiving board. You may also require encoder and decoder ICs, like HT12E and HT12D.
You can refer the following link having details about a similar project

We are not sure about the kind of help you are expecting. Please share more details about the project and your doubts aswell.
