Hall Sensor Velocity Measurement And Counting

Description : 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
