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
