Keyes Hall Switch Magnetic Sensor A3144 Speed Measurement Counting Module Compatible with Microbit

This is a commonly used Hall sensor, which mainly uses A3144 Hall elements. This component is a magnetic sensing circuit composed of a voltage regulator, a Hall voltage generator, a differential amplifier, a Schmitt trigger temperature compensation circuit, and an output stage with an open collector. Its input is magnetic induction intensity, and its output is a digital voltage signal. It is a unipolar switch type Hall sensor that only senses the South Pole magnetic field. When the sensor senses no magnetic field or a North Pole magnetic field, the signal terminal is at a high level; When sensing the South Pole magnetic field, the signal terminal is at a low level.
