Fermion: BMM350 Triple-Axis Magnetometer Sensor for AR / VR (Breakout)

Introduction

The Fermion: BMM350 3-Axis Geomagnetic Sensor is a high-performance magnetometer designed to measure magnetic fields across three axes, functioning as a precise electronic compass. Utilizing Bosch’s patented FlipCore technology, it provides accurate spatial orientation without requiring calibration. While maintaining compatibility with the previous BMM150 series, the BMM350 offers enhanced performance, including lower power consumption and improved measurement capabilities.

Powered by TMR (Tunnel Magnetoresistance) technology, the sensor features a field shock recovery mechanism, ensuring stable and accurate readings even in the presence of external magnetic field disturbances. This makes it ideal for dynamic applications requiring consistent high-precision measurements.

Key Features

Field Shock Recovery for Stable Performance

Equipped with TMR technology, the BMM350 includes a field shock recovery function that minimizes interference from external magnetic fields. This ensures reliable and consistent sensor output, making it well-suited for mobile and dynamic systems.

High Sample Rate for Real-Time Data

Supporting a sample rate of up to 400Hz, the BMM350 delivers real-time, precise measurements. This is essential for applications requiring rapid response times, such as AR/VR systems, AGV (Automated Guided Vehicle) geomagnetic navigation, and drone flight control.

Wide Measurement Range and High Resolution

With a measurement range of ±2000μT across all three axes (XYZ), the BMM350 captures magnetic fields with exceptional accuracy. Its high resolution of 0.1μT allows detection of even the smallest fluctuations, making it ideal for high-precision applications in advanced navigation and motion tracking.
