Hall-Effect Sensor Module Easy Magnetic Sensing for Arduino & DIY Projects

Simple Magnetic Field Detection with Hall-Effect Sensor Technology

Experience hassle-free magnetic sensing with this Hall-Effect Sensor Module, perfect for beginners and electronics hobbyists. Featuring the reliable Allegro A3144EUA digital Hall sensor, this module lets you easily detect the presence of a magnetic field, making it ideal for building magnetic switches, proximity sensors, security systems, and more.

How Does the Hall-Effect Sensor Module Work?

This module uses the Allegro MicroSystems A3144EUA unipolar Hall-Effect sensor. When a magnet approaches the sensor and the magnetic field strength exceeds the threshold (35-450 Gauss), the output transistor switches on, pulling the output pin low. The onboard LED indicator lights up instantly, providing visible feedback that a magnetic field is present.
