Building A Device To Map Magnetic Fields

30 sec read15 views0 listens

A portable magnetic field mapping device has been developed using an ESP32 microcontroller, dual EMS100 Fluxgate sensors, and an Arduino Nano for low-level data processing. This modular hardware architecture demonstrates an efficient way for developers to handle real-time sensor integration and data visualization on integrated touchscreens. While primarily serving geological or specialized investigative fields, the project provides a blueprint for building high-precision environmental monitoring tools that support local heatmap rendering and SD card data export.
