The ACS72981 current sensor module uses the Hall effect to accurately and safely measure AC and DC current, providing electrical isolation of the current path. With a wideband analog output (up to 250 kHz) and low conduction resistance (0.2 mΩ), it minimizes energy loss and offers a fast response time of less than 2 µs. Pololu 5250
Description
The ACS72981 current sensor module is a modern solution based on the Hall effect, providing electrical isolation of the current path. This allows it to be placed anywhere in an electrical circuit, offering a safe and precise measurement. The sensor features a noise-resistant design, eliminating the influence of uniform magnetic fields, such as the Earth's magnetic field. Thanks to the low conduction path resistance (0.2 mΩ) and a multilayer PCB (6 layers, 2 oz copper), energy losses are minimized.
The sensor offers a wideband analog output (up to 250 kHz) proportional to the AC or DC current, with a response time of less than 2 µs. Built-in digital temperature compensation improves measurement accuracy over a wide temperature range.
Various mounting methods allow easy integration of the module into the circuit – you can solder wires directly to the holes, use no-solder ring terminals, or mount screw terminals. The largest holes support wires up to 8 AWG and M3.5 screws, with additional 3.5 mm and 5 mm holes allowing the use of screw connectors or header pins.
The module is perfect for applications requiring precise current measurement, such as energy management systems, battery monitoring, protection circuits, and industrial electronics. Thanks to its electrical isolation, it allows safe current monitoring in high-voltage systems, and its low power consumption makes it suitable for mobile applications and battery-powered devices. The user-friendly interface and compact design make the sensor an ideal choice for both professionals and hobbyists. It can be used in prototyping, testing, and as a component of ready-made measurement systems. Its easy integration and wide range of applications make the ACS72981 an indispensable tool in modern electronics.
