Hi everyone, I've been trying very hard to contruct an analog front end to measure current with an MCU, using a C.T(preferbly) or a sense resistor. Translating them into positive 0-5V.But find no luck as the I need a wide range and good resolution of 5mA.
Requirements :-
Line current : 0 - 10A 50/60hz AC
Resolution :5 mA
I need to translate them into 0-5V to be measure by my MCU to graph the instananeous current waveform, and of coz the rms values, peaks and so on.
The biggest problem is the 5mA requirement.Any help is greatly appreaciated.
