Technical Descriptions

The LM393 Linear Hall Effect Sensor Module is a highly sensitive magnetic field detection sensor designed for Arduino, ESP32, Raspberry Pi, and robotics applications. It uses a linear Hall effect sensor paired with an LM393 comparator to provide both analog (AO) and digital (DO) outputs, making it ideal for projects requiring precise magnetic field measurements or simple threshold-based switching.

This module includes an onboard potentiometer to adjust sensitivity, along with power and output LEDs for easy status indication. Whether you're building a motor speed monitor, proximity detection system, magnetic encoder, or DIY robotics, this sensor delivers stable, accurate, and reliable magnetic field sensing.

Perfect for hobbyists, students, and electronics enthusiasts working on STEM projects or embedded systems.
