MLX90393 software-defined 3-axis magnetometer

摘要

Sensors are primordial to most electronics projects; without them circuits would not (have any) function. Most sensors measure physical quantities that are analogue by nature and using their noise-sensitive signals is not always easy. But digital electronics has come to the rescue and many modern sensors integrate signal processing circuitry and a serial interface. In this article we show you how to use a state-of-the-art tri-axis magnetometer without calculating a single resistor value.
