AH49E Hall Effect Sensor Module

Overview

AH49E Hall Effect Sensor Module

The AH49E Hall Sensor Module is a compact and reliable linear Hall effect magnetic sensor designed to detect the strength and polarity of magnetic fields. Unlike simple digital Hall switches, the AH49E provides an analog voltage output proportional to the magnetic field, making it ideal for measuring magnetic field changes, position, speed, and rotational movement.

This module includes onboard signal conditioning and pin headers for easy connection to Arduino, ESP32, STM32, Raspberry Pi, and other microcontroller platforms. It is perfect for robotics, automation, motor control, and DIY electronics projects.

Whether you're building a magnetic speed sensor, contactless switch, or position detection system, the AH49E offers accurate and stable magnetic sensing in a compact form factor.
