sorry to be negative but those current sensors really aren't very good, plus the ADC of an arduino isn't really accurate enough for the very small voltage changes needed to go down to less than an Amp resolution. A better way imho is to use an ina219 & use a different shunt from ebay. The INA has an built in low noise amplifier which can measure the tiny voltage difference across a shunt.
