About this item

The SparkFun Current Sensor Breakout – ACS723 (Low Current) is a precision analog current sensing module designed for low to moderate current applications. Utilizing the ACS723 Hall-effect sensor, it provides electrical isolation between the measured and sensing circuits, making it suitable for both AC and DC current measurements. The board features an on-board amplifier with adjustable gain, allowing for sensitivity tuning from 2.2 to 22 V/V, enabling accurate detection of currents as low as 10 mA. It operates on a 5V supply and outputs a voltage proportional to the sensed current, facilitating easy integration with microcontrollers and other digital systems. This sensor is ideal for applications such as battery monitoring, power consumption analysis, and motor control systems.
