Description: Small Hall Effect Sensor Module
Small PCB Hall Effect Sensor Module A3144E 49E 3 Pin Hall Sensor Hall Effect Detection Magnetic Switches Speed Counting Sensor Module For Arduino 3 Pin Leads
This module can be used to detect the presence of an magnetic field. If there is an magnetic field present, it will report a high level signal. It can be used in many applications such as RPM sensor (for counting the number of shaft revolutions), Robot speed and distance measurements, door switch and robot arm position sensor. Generally, it can be used for any magnetic field detection.

This Hall Sensor Module used Hall Sensor A3144E. The Hall Sensor measures the Hall Effect, which is a production of a voltage difference across an electrical conductor, transverse to an electric current in the conductor as well as a magnetic field perpendicular to the current. The output of the Hall sensor switches low and turns on when a magnetic field perpendicular to the Hall sensor exceeds the BOP threshold, and it switches high and turn on when the magnetic field disappears. And the comparator circuit that make the output signal more reliability.
