Hi everyone. I am new to this forum and this is my first encounter with Arduino. I For my thesis I need to determine the variation in received signal strength of RFID tags. I have found examples of DIY RFID readers with Arduino but the sketches usually read/write the tags. I was wondering if it could be possible to do this in a manner similar to reading the photo resistor values from an analog input?
Could anyone please guide me on this? Thanks in advance

Reading RFID tags is very different from reading a photo resistor. An Arduino could read signal strength values only if the RFID reader module provides them. For passive tags I'm not sure that "signal strength" is a useful concept. Either you can read the tag, or you can't.
If you are thinking about measuring distances to tags, that is close to impossible.
