    Hi
    i want to transmit temperature from once place to another place through RF. I am using rf 433mhz normal rf modules. For temperature sensing i am using DS1820.

    Anybody have idea over this. How can i transfer data serially through RF with 8051.

    Yes you can use 433mhz rf modules serially with 8051 micros. But keep the baud rate less than 500.
    Give a try and get back if you got any more doubts.

    Thanks for your reply, it got working on baud rate 300.
    Will post more details once i complete the project.

    interface HT12E(ENCODER) between microcontroller and RF module at the transmitter side and HT12D(DECODER) between RF module and microcontroller at the receiver. go through the datasheet of encoder and decoder, your problem will be solved.
