ACS724 40A Hall Effect Current Sensor

This current sensor module is built around the ACS724 IC and measures both AC and DC currents up to 40A. It delivers an analog output sensitivity of 40mV per ampere, enabling precise current monitoring in real time. The module is constructed on a PCB substrate with robust electrical insulation properties, offering reliable signal transmission and long-term stability under repeated use. The sensor provides galvanic isolation between the measured current path and the output circuit, enhancing safety during operation. Its design supports direct integration with microcontroller platforms such as Arduino, requiring no additional calibration for basic use cases. The compact form factor and standard pin layout simplify mounting and wiring in DIY electronics, robotics, energy monitoring, and industrial control applications.
