Hall Sensor Velocity Measurement and Counting Sensor 3144E

Hall Sensor Velocity Measurement and Counting Sensor 3144E

Hall sensor module is used for magnetic field detection, which adopts 3144E Hall Switch Sensor.
Module Interface Description

VCC: connect to positive 3.3-5V
GND: connect to negative
DO: Digital signal output on module, outputs low level when magnetism available
AO: Hall real-time voltage output

There are two outputs on the module

AO, Hall real-time output
DO, the Hall signal output after being regulated by the comparator
