Featuring onboard power indication and compact design, it’s ideal for industrial, robotic, and scientific applications requiring non-intrusive current monitoring. ## Description Product Description The ACS712 5A Current Sensor Module offers a compact, reliable, and accurate method for sensing both AC and DC current. Based on the Hall-effect principle, this module integrates a precision linear Hall circuit and a copper conduction path on the same chip. As current flows through the copper path, it generates a magnetic field sensed by the Hall IC, converting it into a proportional analog voltage signal. With a current detection range of -5A to +5A, it is ideal for measuring low-current loads with high sensitivity (100mV/A). The module provides galvanic isolation and high accuracy, making it suitable for use in overcurrent protection, power monitoring, switching regulators, battery management systems, and more. This module interfaces easily with microcontrollers such as Arduino, ESP32, STM32, and Raspberry Pi. The analog voltage output can be read directly from the ADC (analog-to-digital converter) pin of your development board, enabling real-time current monitoring. It is compact and robust, designed for plug-and-play integration into your electronic circuits. Specification Sensor IC: ACS712ELC-5A Operating Voltage: 4.5V to 5.5V DC Current Measurement Range: -5A to +5A Sensitivity: 100mV per Ampere Output: Analog voltage (linear with current) Output Response Time: 5µs Isolation Voltage: 2.1kV RMS Dimensions: 32mm x 13mm x 13.5mm Weight: 5g Operating Temperature: -40°C to +85°C, Mounting: Through-hole Feature Hall-effect based linear current sensor Measures both AC and DC currents up to ±5A 100mV/A sensitivity for easy calibration Electrically isolated signal output Compatible with Arduino, ESP32, STM32, etc. Application Battery management systems Motor current monitoring Power supply load detection Inverter and solar system current sensing Package Include:- 1x ACS71205 Hall Current Sensor Module 5A Model Review: One faulty sensor - I ordered two current sensor.
