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 ideal for DIY electronics, robotics, and automation projects.
