I need help regarding Radio Frequency module.I just want to receive the output of the IR sensors mounted on my robot using RF module.

A transmitter will be mounted on the robot and the receiver part will be interfaced with the PC.

There are diff modules available like RF ASK Receiver Module,RF-FSK-Receiver Module. Which one will be suitable for me and what's the difference between the two?

Awaiting an early reply.Thanks in advance.

ASK -- amplitude shift key
FSK-- Frequency Shift Key

Difference is in modulation technique used, and refer to datasheet, many sites have the datasheets for the rf module, you could use the Holtek encoded, decoder ic's in conjunction with the transmitter/receiver
