The ACS72981 current sensor module uses the Hall effect to precisely and safely measure DC current while 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 power loss and offers a fast response time of less than 2 µs. Pololu 5284
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 the electrical circuit, ensuring safe and precise measurements. The sensor features an interference-resistant design, eliminating the impact of uniform magnetic fields, such as the Earth’s magnetic field. With its low conductor resistance (0.2 mΩ) and multilayer PCB (6 layers, 2 oz copper), energy losses are minimized.
The sensor provides a wideband analog output (up to 250 kHz) proportional to AC or DC current, with a response time below 2 µs. Built-in digital temperature compensation ensures accurate measurements across a wide temperature range.
The module uses a multilayer PCB, ensuring high durability and reliability. Large mounting holes allow connection of wires up to 2 AWG or the use of ring terminals. Alternatively, holes with 2.54 mm, 3.5 mm, and 5 mm pitch are also available, although they are not recommended for high-current applications.
This module is ideal for applications requiring precise current measurement, such as energy management systems, battery monitoring, protection circuits, and industrial electronics. Thanks to its electrical isolation, it enables safe current monitoring in high-voltage systems, while its low power consumption makes it suitable for mobile and battery-powered devices. Its user-friendly interface and compact design make the sensor an excellent choice for both professionals and hobbyists. It can be used in prototyping, testing, or as part of finished measurement systems. Easy integration and a wide range of applications make the ACS72981 an indispensable tool in modern electronics.
