Description

The M5Stack Hall Effect Unit (A3144E Hall Sensor) is a compact Hall sensor module for detecting magnetic fields, proximity, position, and speed-related events. It integrates three A3144E Hall effect switches, with logic processing handled by a 74HC08D gate IC.

The M5Stack Hall Effect Unit (A3144E Hall Sensor) outputs a low-level signal when an S magnetic pole approaches the front side of the sensor or an N magnetic pole approaches the back side. The onboard red LED lights when the magnetic state is detected, making the unit useful for door magnetic alarms, magnetic proximity sensing, rotation detection, and other embedded projects.
