The MLX90393 is a tri-axial magnetic sensor capable of sensing very small fields (like the Earth’s magnetic field) while behaving as one would want and expect during saturation in larger fields (like a near by magnet). It turns out the favorite HMC5883L and other such sensors that are intended for compass applications have a low dynamic range but also strange and undefined behavior in large fields. Ted Yapo did an incredibly extensive characterization of the sensor over on Hackaday. He published his controlled experiments testing a few sensors and found the MLX90393 to be superior.
The MLX90393 can be used as a compass sensor but also works well as a non-contact controller (joystick), flow meter (with magnetic impeller), or a linear actuator positional sensor.
We do not plan to regularly produce SparkX products so get them while they’re hot!
