How to implement 315mhz RF wireless into my circuit?

Hi All

Im new to here.
I did up a heart rate circuit, and the output is a LED which will blink on very heart beat detected.

I’ve gotten myself a pair of 315mhz RF transmitter and receiver.

Is it possible that I output the circuit to the RF transmitter. then a LED to the receiver on a separate circuit, but will still blink on every heart beat.

This is the circuit i have built:

D2 is the photodiode, where a finger will be placed and shone with a LED. The LED at the right end of the circuit is the LED which will blink on every heartbeat detected.

This is the RF module i have gotten: … -p-76.html

How should i go about doing that?
