Hi Sir,

I would like to design a project that functions depending on the signal strength of a RF signal. I read about received signal strength indicator, and somehow I think this is useful info. The concept of the project is to vary the output (e.g. a transducer) depending on the signal strength of an oncoming transmitter. What IC can i use? Thanks

Hello Michael,

There are many ic's that can do this for you. What you want to measure is "Receiver signal strength indicator" or RSSI. Most IC's have this available as a register in the IC and can be accessed through a firmware command.

I should mention that RSSI is not a very accurate measurement. Environmental noise and distance between the receiver and transmitter will affect the RSSI reading. So if you want to use it as a precision measurement RSSI is not the best choose.

Here are a number of manufactures that provide RSSI with their IC.
