Sense the magnetic fields surrounding us with this handy triple-axis magnetometer (compass) module. Magnetometers can sense where the strongest magnetic force is coming from, generally used to detect magnetic north, but can also be used for measuring magnetic fields. This sensor tends to be paired with a 6-DoF (degree of freedom) accelerometer/gyroscope to create a 9-DoF inertial measurement unit that can detect its orientation in real-space thanks to Earth’s stable magnetic field.
The Adafruit MMC5603 – Triple-axis Magnetometer guide has everything you need to get started with using this magnetometer. There’s pages for overview, pinouts, CircuitPython, Arduino and download resources.
