Description:
The Waveshare BMM150 3-Axis Magnetometer Sensor is a compact, high-precision digital compass module engineered for accurate magnetic field measurement across X, Y, and Z axes. Leveraging advanced magnetoresistive technology, this sensor delivers reliable heading and orientation data, making it ideal for use in navigation systems, augmented reality, robotics, and a wide range of IoT and embedded applications.
Its 3-axis capability allows for precise detection of the Earth's magnetic field in all directions, providing essential data for compass functionality and spatial awareness. With its digital interface and versatile compatibility with platforms like Arduino, Raspberry Pi, and other microcontrollers, the BMM150 is an essential tool for developers building directional sensing, motion tracking, or position-aware systems.
