About this item

The DFRobot Gravity: Linear Analog Hall Effect Sensor offers precise magnetic field detection with a range of ±1200 Gauss (GS). Operating between 3.3V and 5.5V, it provides an analog voltage output proportional to the magnetic field strength, facilitating easy integration with microcontrollers like Arduino and micro:bit. The sensor features bipolar sensing capabilities, detecting both north and south magnetic poles, and includes a low-noise output for stable readings. Its compact design (27x32mm) and PH2.0-3P interface ensure compatibility with various platforms. Applications include current detection, motor control, magnetic field measurement, and metal detection.
