The ACS712 5A Current Sensor is an accurate, highly reliable Hall-effect sensing module engineered for real-time AC and DC current monitoring. Built around the ACS712ELC-5A chip, it provides bidirectional current measurement within a $\pm 5\text{A}$ range with minimal power loss. As current passes through the integrated low-resistance copper path, the chip generates a linear analog output voltage ($185\,\text{mV/A}$) proportional to the measured load. Compatible with 5V systems and easily read via standard ADC pins on Arduino, ESP32, and Raspberry Pi, it serves as an excellent foundation for power monitoring, overcurrent protection, and smart energy metering projects.
