3D Magnetic Flux Meter Using Arduino

The 3D Magnetic Flux Meter project centers around an Arduino Uno microcontroller that continuously reads spatial magnetic data and outputs it visually. At the heart of the sensing subsystem is the LIS2DML sensor, which communicates with the Arduino. While the LIS2DML is fundamentally a MEMS accelerometer, it detects changes and forces in its immediate environment, which can be calibrated to measure tri-axial magnetic or motion-based flux phenomena. The Arduino queries this sensor to retrieve real-time numerical readings corresponding to the X, Y, and Z axes. Once the microcontroller processes these spatial coordinate metrics, it formats the data for output. Connected via standard interface wiring, an OLED display receives the processed data strings from the Arduino, rendering clear textual and numerical representations of the magnetic forces acting on each axis. The entire electronics assembly is powered locally by a compact 3V battery, allowing the device to remain entirely portable while logging or displaying magnetic fields. Programming is handled via the Arduino IDE, utilizing dedicated libraries—specifically the LIS2DML sensor library to handle register communications and the U8g2 graphics library to drive the pixel layout on the OLED screen.
