Gravity BMM350 3-Axis Magnetometer Sensor for AR/VR

Discover precise magnetic navigation with the Gravity BMM350 Magnetometer. This sensor captures magnetic fields on three axes and offers you enhanced accuracy through innovative TMR technology. With an extremely low power consumption of only 200 µA, it is perfect for battery-operated devices. The Field-Shock-Recovery function ensures that external magnetic disturbances have no effect on measurement accuracy. With a maximum sampling rate of up to 400 Hz and support for I3C protocols, this sensor is ideal for applications in AR/VR, navigation, and robotics. It offers a wide measurement range of ±2000 μT and operates reliably in temperatures from -40 to +85°C. With its compatibility with the previous BMM150 series, it can be easily integrated into existing projects. This compact sensor is versatile and ensures precise navigation and orientation.
