AH49E linear Hall effect sensor module

The AH49E Linear Hall Effect Sensor Module is a sensitive magnetic field sensor designed to detect magnetic field strength and polarity with a linear analog output. Unlike digital Hall sensors, the AH49E provides a voltage output that varies proportionally with the applied magnetic field, making it ideal for position sensing, speed measurement, and current detection applications.

The module operates from a 5V power supply and produces an analog output centered around 2.5V at zero magnetic field, allowing easy interfacing with microcontrollers such as Arduino, ESP32, STM32, and PIC through an ADC pin. Its compact and breadboard-friendly design makes it perfect for prototyping and educational use.

The AH49E module is widely used in rotary position sensing, motor speed detection, magnetic proximity sensing, contactless switches, and robotics projects, offering stable performance and low noise in embedded systems.
