The ACS712 30A Hall Effect Current Sensor Module<\/strong> is a reliable and easy-to-use solution for measuring AC and DC current up to \u00b130A<\/strong>. Based on the original Allegro ACS712 Hall-effect IC<\/strong>, this module provides an isolated analog voltage output<\/strong> proportional to the current flowing through the onboard copper conductor.<\/p>\n

Designed for seamless integration with Arduino, ESP32, Raspberry Pi (with ADC), and other microcontrollers<\/strong>, the sensor outputs VCC\/2 at zero current<\/strong>, making it ideal for bidirectional current sensing. It is widely used in power monitoring, motor control, battery management systems, and IoT projects<\/strong>.<\/p>\n

This module offers electrical isolation between the measured current path and the control circuit, ensuring safe and accurate current measurement<\/strong> in both hobby and professional applications.<\/p>\n
