Current Sensor - ACS712T

The ACS712T Current Sensor is a precise module based on the Hall Effect, designed for both AC and DC current measurement. It provides an economical and reliable solution for overcurrent protection, battery chargers, and power monitoring by outputting an analog voltage proportional to the current flow. Key Features: Bipolar Sensing: Capable of measuring both positive and negative current (AC and DC). Galvanic Isolation: The sensing terminals are electrically isolated from the sensor leads, ensuring safe operation at high voltages. Low Noise Path: Internal copper trace allows for low-resistance current flow (approx. 1.2 m$\Omega$). Stable Output: Features a precise offset voltage that centers at VCC​/2 for zero current readings. Compact Design: Available in 5A, 20A, or 30A variations to suit different load requirements.
