A3144 Linear Hall Effect Magnetic Sensor Module with LM393

This magnetic linear Hall effect sensor module features an onboard A3144 sensor and an LM393 comparator with an adjustable threshold. Operating at 3.3V or 5V, it detects magnetic fields to trigger digital signals for interactive hardware projects. It is well suited for learners, makers, and electronics enthusiasts experimenting with magnetic sensing.

Adjustable threshold detection

The module uses an onboard LM393 comparator circuit to provide an adjustable detection threshold for magnetic fields. When the sensor detects a magnetic field, it triggers a clean digital switching signal.

Flexible operating voltage

Designed for low-power electronics, the board supports both 3.3V and 5V supply voltages for straightforward project integration.

Simple project implementation

The module can be connected directly to a microcontroller digital input to drive indicator LEDs or trigger warning circuits when a magnetic field is present.
