Magnetic induction intensity meter

 
Overview

51 microcontroller magnetic induction intensity meter

The voltage of the linear Hall is read through the ADC and converted into magnetic induction intensity.
What is measured is the size of the magnetic induction intensity vector perpendicular to the Hall plane and facing the direction of the Hall screen printing.
In other words, if the Hall screen printing faces the N pole facing the N pole, it will be a negative number.
The accuracy is not bad, and it is okay for fun. If you want high accuracy, please use 16 Bit ADC

Note that the installation direction of the Hall is facing the digital tube, which is opposite to the silk screen direction.
