Magnetometer 3D Field Mapper Kit with Arduino Uno + MPU6050
Calibrate and Map 3D Magnetic Fields with Arduino Uno & QMC5883L Kit
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Unlock the invisible world of magnetic fields: assemble a professional 3D magnetometer mapper that reads raw sensor data, applies hard-iron calibration, and renders a live ellipsoidal field map on a 1.8-inch TFT display. Whether you're preparing for a Smart India Hackathon demo, a B.Tech ECE capstone, or deep-diving into sensor fusion algorithms, this kit transforms theory into functioning hardware in about 5-6 hours.
What You'll Build
A fully assembled magnetometer calibration system that rotates the QMC5883L on a 3D sphere and corrects hard-iron distortions. The calibrated output is streamed to the TFT as a real-time ellipsoidal map, with data logged to a microSD card alongside RTC timestamps for analysis.
What You'll Learn
- Hard-iron calibration algorithm implementation for 3-axis magnetometers
- Sensor fusion between MPU6050 gyroscope/accelerometer and QMC5883L magnetometer
- TFT display integration using ST7735 over SPI with Arduino Uno
- Data logging to microSD with DS3231 RTC for time-stamped magnetic field datasets
