how to send analog values through wireless communication like rf433hz or so

how to send analog values through wireless communication like rf433hz or so to arduino.I basically wanna send my pot/other sensor values to arduino through wireless communication and it should be more of economical. Thanks in advance.

Use the VirtualWire library. It can send and receive any message, up to a certain number of bytes, so that message could contain analog values.

thats okay bro but what module i have to use for that
