đ Product Description / āĻĒāĻŖā§āĻ¯ āĻŦāĻ°ā§āĻŖāĻ¨āĻž
English:
The ACS712-30A Current Sensor Module is a Hall-Effect-based current measurement module capable of measuring both AC and DC current up to Âą30A. It provides an analog voltage output proportional to the current being measured, making it easy to interface with microcontrollers such as Arduino, ESP32, STM32, and Raspberry Pi (with ADC). This module is widely used in battery monitoring, motor control, power management, and solar energy projects.
