Current Sensor ACS712-30A

Description

The ACS712-30A is a current sensor module that can detect positive and negative currents ranging from minus 30 Amps to positive 30 Amps. It operates at 5V DC and converts the current flow through the sensor to an output voltage. The output voltage starts at 1/2Vcc (or 2.5V) for no current flow and moves up 66mV per amp for positive current.

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.

This AC721 current module is based on the ACS712 sensor, which can accurately detect AC or DC. The maximum AC or DC that can be detected can reach 30A, and the present current signal can be read via the analog I / O port of Arduino.
