Method to measure RSSI of RF signal

Projects General Guidance
1

i am working on a method to measure the received signal strength for an RF transmitter and reciever circuit i made, the basic concept is that when the receiver is close to the transmitter, the RSSI is high, and it becomes lower when the receiver moves away from the transmitter.

i have tried measuring the voltage with an avometer and it is successful, but my question now is : is there a function or a way where i can measure the received voltage or RSSI using arduino uno? i need the arduino to measure the value and maybe store it in a variable, is there a function for that?

thank you in advance :slight_smile:

Many RF modules report the RSSI.

Unfortunately, RSSI is almost useless as a measure of distance, because other factors affect it more strongly than distance.
