Dear community, I am looking for the measuring accuracy for Arduino Uno for the voltage inputs. I know It can measure up to 5V, but I will be measuring from 0 to 5 mV from a sensor, What would be the accuracy with Arduino? I am new to Arduino so any information you can provide me will be apprecia…

For measuring 0 to 5mV, amplifying the signal using an op amp or an instrumentation amplifier (depending on your exact requirement) is your best bet.
