I have been thinking about making an ac current metering device and I cam across a split core ac current sensor. I'm not exactly 100 percent sure what the output of this sensor will be like but on the amazon page it claims to output 100ma. Since the arduino will not handle 100ma input what would be my options to to use the arduino to measure from the splitcore?
From what I know about transformers to go from 100 amps to 100ma there must be a lot of turns on those wires you see sticking out of there. So that means it could be a large voltage plus it is alternating at 50 -60 Hz.
So your probably talking using voltage dividers and rectifying if you want to measure with an arduino.
