Gravity: BMM350 Triple-Axis Magnetometer Sensor for AR / VR

The DFRobot Gravity: BMM350 3-axis geomagnetic sensor is a marvel of modern sensor technology designed to precisely measure magnetic fields along three axes, functioning effectively as a digital compass. It features Bosch's renowned FlipCore technology, ensuring consistent spatial orientation without the hassle of calibration. Building on the foundation of the previous BMM150 series, the BMM350 offers superior performance with improved measurement capabilities and a focus on energy efficiency, which is crucial for long-term applications.

One of the standout features of the BMM350 is its resilience against magnetic interference, thanks to the groundbreaking TMR (tunnel magnetoresistance) technology combined with a unique field shock recovery mechanism. Imagine a resilient umbrella that flexes against wind gusts without flipping inside out - this sensor demonstrates similar robustness, maintaining high-precision measurements even in fluctuating magnetic environments.

For those needing swift and efficient data handling, the BMM350 supports a high sample rate of up to 400Hz. This capability is particularly beneficial in applications involving augmented and virtual reality or for navigational tasks in automated guided vehicles and drones. In addition, the introduction of I3C communication enhances data transmission speeds, allowing for seamless integration of multiple sensors with reduced wiring clutter, much like shifting from a twisted earphone cable to a single Bluetooth connection.

The sensor operates with remarkable precision and is designed to consume minimal power, drawing only 200μA when sampling at 100Hz. This efficiency is ideal for battery-operated devices where power conservation is essential. It is capable of measuring a wide range of magnetic fields, from the subtle to the intense, accommodating various complex applications ranging from consumer electronics to sophisticated industrial systems.
