Fermion BMM350 is a 3-axis digital geomagnetic sensor using TMR technology. It measures 3-axis magnetic field strength with low power (200uA), low noise (190nT rms@xy, 450nT@z), high range (±2000μT), and selectable sampling rates (400~25/16Hz). Its unique field shock recovery ensures robustness to external fields and high accuracy. Applications include indoor/outdoor navigation, electronic compasses, and AR/VR development.

1. Example Code for Arduino-Get All State
Get all the config status, self test status; the sensor turns to sleep mode from normal mode after reset. Experimental phenomenon: serial print the sensor config information and the self-test information
2. Example Code for Arduino-Get Geomagnetic Data
Get the geomagnetic data at 3 axis (x, y, z), get the compass degree, the angle formed when the needle rotates counterclockwise from the current position to the true north. Experimental phenomenon: serial print the geomagnetic data of x-axis, y-axis and z-axis and the compass degree
3. Example Code for Arduino-Threshold Interrupt
This article demonstrates how to use a BMM350 magnetometer with Arduino to trigger interrupts when geomagnetic data surpasses set thresholds, providing detailed instructions on hardware setup, software configuration, and coding.
