Description

The 4-Pin Linear Magnetic Hall Switch Sensor Module is a compact, high-precision device that detects magnetic fields and converts them into voltage signals using Hall effect technology . Designed for Arduino, ESP32, STM32 , and similar microcontrollers, it’s perfect for speed measurement, rotation counting, position sensing, and proximity detection . The module offers both analog (AO) and digital (DO) outputs, allowing it to function as either a linear magnetic field sensor or a magnetic switch . An on-board potentiometer enables easy sensitivity adjustment, while built-in indicator LEDs provide clear visual feedback. Reliable, responsive, and easy to integrate, this Hall sensor module is id
