Keyestudio ACS712-30A Current Sensor for Arduino

The Keyestudio ACS712-30A Current Sensor is a precise, Hall Effect-based module designed to measure both positive and negative AC or DC currents up to 30A. It is an ideal choice for South African students, makers, and hobbyists building power monitoring systems, battery chargers, or smart energy projects.

Hall Effect current sensing

This module utilises the ACS712ELC-30A chip to measure current intensity based on the Hall Effect. For accurate readings, ensure the sensor is kept away from external magnetic fields during operation.

Bi-directional current detection

The sensor is capable of detecting up to 30A of positive and negative current. This makes it highly versatile for monitoring both charging and discharging states in battery systems.

Onboard power indicator

Operating on a standard 5V power supply, the board features an integrated power indicator LED. This provides immediate visual confirmation that your sensor is powered and ready.

Easy Arduino integration

Designed with a simple interface, this sensor easily connects to Arduino and other microcontrollers. It allows students and makers to quickly implement real-time power monitoring in their builds.

Linear analog output

The module provides a convenient analog output of 66mV per Ampere of measured current. When no current is flowing, the output voltage sits at half of the supply voltage (VCC/2).
