ACS712 - 30A Range Current Sensor Module
Description:
ACS712 - 30A Range Current Sensor Module is a highly reliable and efficient current sensing device based on Hall Effect technology, designed to measure both AC and DC currents up to ±30 Amperes (A). Developed by Allegro Microsystems, this module provides electrical isolation between the sensed current and the output signal, making it ideal for real-time monitoring in industrial, commercial, and DIY electronic applications.ACS712-30A module outputs an analog voltage signal linearly proportional to the current passing through it, making it easy to interface with Arduino, ESP32, Raspberry Pi, and other microcontrollers for accurate current measurements.
Features:
1. Capable of measuring both AC and DC currents
2. ±30A current measuring range
3. Output voltage proportional to input current
4. High isolation between measurement path and output signal
5. Fast response time suitable for dynamic current measurement
6. Compact size and easy integration with microcontrollers
7. Stable, accurate, and noise-resistant performance
8. Simple 3-pin connection interface
9. Low power consumption
