BNO055

The BNO055 is a sophisticated sensor module developed by Bosch Sensortec. It integrates a triaxial 14-bit accelerometer, a triaxial 16-bit gyroscope with a range of ±2000 degrees per second, and a triaxial geomagnetic sensor. What sets the BNO055 apart is its ability to combine these sensors with a microcontroller running a Bosch Sensortec FusionLib software, making it a "smart" sensor that outputs fully-calibrated sensor data and sensor fusion signals.
The BNO055 is designed for applications requiring precise orientation data, such as augmented reality, virtual reality, robotics, and drones. It offers three output modes: Accelerometer, Gyroscope, and Magnetometer output; Inertial Measurement Unit (IMU) output; and Absolute Orientation (Euler Vector, Quaternion output). This versatility allows it to be used in various projects without the need for complex sensor fusion algorithms.
Additionally, the BNO055 features built-in temperature and calibration sensors, which enhance its performance by providing consistent readings under varying environmental conditions. It communicates via I2C or UART, making it easy to integrate with microcontrollers like Arduino and Raspberry Pi.
