ACS714 Current Sensor Carrier -5 to +5A
Description: This board is a simple carrier of Allegro’s ±5A ACS714 Hall effect-based linear current sensor, which...
Harshit the spec of 0.185V/A means you will get 0.185 Volts per 1000mA . So, to get the voltage for 1 mA you have to divide 0.185 V, i.e., 185 mV by 1000. Which gives you 0.185mV or 185 uV. You need to have a very high accuracy amplifier to measure this kind of Voltage. It is better to have a differential amplifier of 100 gain.
