Hi Im using the following RF module

http://www.apogeekits.com/rf_receiver_module_rx433.htm

on an embedded board with the PIC16F628A. Sadly, I realized that the signal strength was in analog form and couldn't get any ideas to get the RSSI reading off the pin because well my PIC is digital DUH!.

My basic idea was

1. To get the RSSI value from my Receiver
2. Send it to the PIC
3. Link the PIC to a PC via RS232
4. Plot a graph of time vs RSSI of the receiver (so I can make out how close my TX is to my RX)

I thought it was bloody brilliant at first but ive hit a dead end here. Any ideas on getting the RSSI data to my PC from this receiver would be nice.

Thanks in Advance

 

Using RSSI to locate an object

Ive already gone through this post. I dont have to locate an object as in that post. Just need to know if the TX has crossed a certain line at a distance from the RX. (Like a vehicle (TX) passing under a traffic signal(RX)).
