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 5273
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 while ensuring safe and accurate measurements. The sensor features an interference-resistant design, eliminating the effects of uniform magnetic fields such as Earth's field. With its low conductive path resistance (0.2 mΩ) and a 6-layer PCB with 2 oz copper, energy losses are minimized.
The sensor offers a wideband analog output (up to 250 kHz) proportional to AC or DC current, with a response time under 2 µs. Built-in digital temperature compensation improves measurement accuracy across a wide temperature range.
The module uses a multilayer PCB to ensure high durability and reliability. Large mounting holes support connections using up to 2 AWG wires or ring terminals. Additionally, there are mounting holes with 2.54 mm, 3.5 mm, and 5 mm pitch, although these 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. Its electrical isolation allows for safe monitoring of high-voltage systems, while low power consumption makes it suitable for mobile and battery-powered applications. With a user-friendly interface and compact design, the sensor is an excellent choice for both professionals and hobbyists. It can be used in prototyping, testing, and as a component in complete measurement systems. Easy integration and wide application range make the ACS72981 an indispensable tool in modern electronics.
