The ACS712 Current Sensor is a result of Allegro MicroSystems that can be utilized for exact estimation of both AC and DC flows. This sensor depends on Hall Effect and the IC has a coordinated Hall Effect gadget.

Coming to the output of the ACS712 Current Sensor, it creates a simple voltage that is relative to AC or DC flows (whichever is being detected).
