RF Txr and Rxr 433.9MHz

Hello Guys,

After a huge gap i came to edaboard forums, here is my doubt i need to connect my rf Rxr antenna(433.9MHz) and it should be communicate with Rf Tranmitter antenna.... The thing i neeed is should i could encoder and decoder OR shall i connect my sensor directly to RF antenna.

If u guys have any ideas to implement .. please give the circuit ideas or some useful links to study .... I want to connect a sensor in RF and it should be controlled by AT89c51....

The modules you are refering to are mere ASK data transmitters. You have to modulate the input with the data you expect to transmit and receive. You may control these LPD's (Low power devices) with any popular microcontroller...If you are looking for professional remote control kits, you may have a look at www.united77.com/projects.htm, where two RF remote kits are available with different functions........Cheers
