BDD ACS712 30A Current Sensor Module AC DC Current Measurement Board

The BDD Current Sensor Module 30A is a high-performance current sensing module built around the trusted ACS712ELCTR Hall-Effect Current Sensor IC, providing accurate and reliable measurement of both AC and DC currents up to 30A. Designed for use in power monitoring, motor control, battery systems, renewable energy projects, and embedded electronics, this compact module offers a simple and effective way to monitor electrical current while maintaining electrical isolation between the sensing circuit and control electronics.

Using advanced Hall-effect sensing technology, the ACS712 detects current flow without requiring a direct electrical connection between the measured conductor and the output circuitry. This isolation enhances safety and protects sensitive microcontrollers and monitoring equipment from high-current circuits.

The module measures currents from 0A to 30A, making it suitable for higher-power applications where accurate current monitoring is essential. The sensor produces an analog output voltage proportional to the measured current, allowing straightforward interfacing with ADC-equipped devices such as Arduino, ESP32, Raspberry Pi, STM32, PIC, and other microcontroller platforms.

At zero current, the output voltage is approximately VCC/2, enabling the detection of current flowing in either direction. This makes the module ideal for bidirectional current sensing applications including battery charging and discharging systems, motor drive monitoring, and power management systems.

Its compact PCB layout incorporates convenient screw terminal connectors for secure wiring and standard 2.54mm pin spacing for easy integration into prototyping boards and development platforms. The low-resistance internal conductor minimizes power loss and heat generation, ensuring efficient operation even in continuous monitoring applications.

Whether you're building a smart energy monitor, motor controller, battery protection system, or industrial automation project, the BDD ACS712 30A Current Sensor Module provides dependable current measurement with excellent ease of use.
