Product Overview

Includes a precise, low-offset, linear Hall circuit using a copper conduction path located near the surface of the die. Applied current flowing through this copper conduction path generates a magnetic field that the Hall IC turns right to a proportional voltage. Sensing and controlling current flow is a basic necessity in a huge array of programs such as, over-current security circuits, battery chargers, switching mode power supplies, electronic watt meters, programmable current sources, etc.. This ACS721 present module relies on ACS712 sensor, which could correctly detect AC or DC current. The most AC or DC which may be discovered can attain 20A, along with the current current signal could be read through analog I / O interface of Arduino.
