Current Sensor Module ACS712 30A
In Stock
Categories: Current Sensors
Overview
The ACS712 30A Current Sensor Module is a compact and accurate module for measuring both AC and DC currents up to ±30 Amperes. It is based on the Allegro ACS712ELC-30A Hall-effect sensor IC, which provides electrical isolation and a linear analog voltage output proportional to the current.
This module is ideal for current sensing in microcontroller-based projects such as Arduino, ESP32, Raspberry Pi, and other development platforms. It helps in monitoring power consumption, detecting overload conditions, and enabling intelligent control in energy-sensitive applications.
