ACS712 - 5A Range Current Sensor Module
Description:
ACS712 - 5A Range Current Sensor Module is a highly popular and reliable Hall-effect-based linear current sensor used to measure both AC and DC currents accurately. Developed by Allegro Microsystems, the ACS712 sensor is designed for easy integration with microcontrollers like Arduino, ESP32, Raspberry Pi, and other embedded systems.
Features:
1. Measures both AC and DC currents
2. Linear Analog Voltage Output proportional to Current
3. Galvanic Isolation between measurement and control circuits
4. Low-noise analog signal path
5. Fast response time
6. High accuracy and sensitivity
7. Built-in filtering for stable readings
8. Small, compact module
9.Fully integrated Hall-effect based sensing
