The 30A range Current Sensor Module ACS712 consists of a precise, low-offset, linearHall circuitwith 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 theHall ICconverts 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.

Note:

ACS712 is based on the principle of the Hall test, please use this field to avoid an impact!
