3-axis magnetometer - MMC5603 - STEMMA QT / Qwiic - Adafruit 5579.

What is a magnetometer? What is a magnetometer for? We rush to answer. It is a special research instrument used to precisely determine the magnetic field - to measure its direction and size. Colloquially speaking - a magnetometer is a digital compass, also used to detect magnetic north.

Why do I need a magnetic field measurement? Thanks to it, you can determine the coordinates and orientation of an object, e.g. a drone or a robot. The magnetometer belongs to the group of IMU sensors, which are used in many applications related to widely understood automation and robotics, navigation systems, as well as during monitoring and compensation of vibrations. They are commonly found in smartphones, tablets and various types of video game controllers.
