PGSA2Z ACS712 30A Range Current Sensor Module

DESCRIPTION

The 30A 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, over-current protection circuits, battery chargers, switching mode power supplies, digital watt meters, programmable current sources, etc. The maximum AC or DC that can be detected can reach 30A, and the present current signal can be read via analog I/O port of Arduino.
