SunFounder Switch Hall Sensor Module Compatible with Arduino and Raspberry Pi;

Introduction
A switch Hall sensor module that is composed by a switch Hall sensor, resistor and capacitor in an integrated circuit.
For your reference:
Based on the Hall Effect, a Hall sensor is a one that varies its output voltage in response to a magnetic field. Hall sensors can be categorized into linear (analog) Hall sensors and switch Hall sensors. A switch Hall sensor consists of voltage regulator, Hall element, differential amplifier, Schmitt trigger, and output terminal and it outputs digital values.

Application
The module can be applied to measurement of revolution, revolving speed, wind speed, flow speed, proximity switch, door lock notification device, alarm, auto-control circuit, etc.
