I want to measure AC current with an Arduino-type device.
I am currently selecting a current sensor.
A 10 bit ADC gives 1023 points. At 5v that is 5v/1023 = 4.9mV
A current sensor with 185mV/A thus gives 26mA (4.9mV/185mV/A) per step.
A current sensor with 800mV/A gives 6.125mA per step.
Does this mean that current sensors with a higher mV/A are better in terms of accuracy of results?
(Obviously a ADC with more resolution would help)
