20A ACS712 Current Sensor Fasteners and Screws In terms of performance20A ACS712 Current Sensor The 20A ACS712 Range Current Sensor Module ACS712 consists of a precise, low offset, linear Hall circuit with a copper conduction path located near the surface of the die. Applied current flowing through this copper conduction path generates a magnetic field in which the Hall IC converts into a proportional voltage. Sensing and controlling current flow is a fundamental requirement in a wide variety of applications including,
