The A3144 Hall Effect Sensor Module is a breakout board version built around the A3144 Hall effect chip, featuring VCC, GND, DO, and AO pins, 2mm mounting holes for secure installation, operating from 3.3V to 5V DC. The hall sensor module’s solid-state design detects magnetic fields using semiconductor physics, with no mechanical contacts that touch or wear, unlike reed switch-based magnetic sensors.
This a3144 hall sensor price reflects a more complete breakout board compared to the bare A3144 component switch — adding mounting holes for secure chassis or enclosure attachment plus both digital and analog output pins for flexibility. The a3144 hall effect sensor arduino’s digital output gives a simple HIGH/LOW magnetic presence signal, while the analog output can be read for relative magnetic field strength, useful when distance-to-magnet estimation matters beyond a simple on/off trigger.
this hall effect sensor module’s 2mm mounting holes require careful screw selection during installation, as oversized screws or excessive tightening pressure near the sensor IC could risk component damage. This StemVolt module is well-suited for engineers building secure-mounted magnetic detection systems and practical RPM counting electronics projects.
