Cảm biến DFRobot Fermion: BNO055 Intelligent 9-axis Sensor (Breakout)

Cảm biến DFRobot Fermion: BNO055 Intelligent 9-axis Sensor (Breakout) đo được 9 thông số bao gồm: ba trục gia tốc kế 14-bit (accelerometer), ba trục con quay hồi chuyển 16-bit (gyroscope), ba trục từ trường (geomagnetic) và được tích hợp vi điều khiển tiền xử lý 32-bit giúp canh chỉnh các thông số chính xác mà không cần sử dụng các thuật toán phức tạp, thích hợp cho các ứng dụng cân bằng, máy bay không người lái, drone,...

BNO055 is a new sensor IC for implementing an intelligent 9-axis Absolute Orientation Sensor. It is a system in package, integrating a triaxial 14-bit accelerometer, a triaxial 16-bit gyroscope, a triaxial geomagnetic sensor and a 32-bit microcontroller. At just 5.2 x 3.8 x 1.1 mm³, it is significantly smaller than comparable discrete or system-on-board solutions and also is the sensor-hub product of the smallest size that supports Windows 8.1 at present. BNO055 is able to provide not only single data of the three kinds of sensors (accelerometer/gyroscope/geomagnetic), but also integrated data, such as quaternions, Euler angles or vectors. Besides, the built-in MCU frees the users from the complexities of algorithm processing, which provides application support in many aspects for smart phone, wearable device and so on.
