BlueDot BNO055 9-Axis IMU

The BNO055 absolute orientation sensor is an amazing device. It integrates an accelerometer, a gyroscope and a 32-bit microcontroller in a single package. Not only can you read the sensors at the same time, but a fusion algorithm running on the on-board microcontroller analyzes all the measured data and calculates the orientation of the device in space.

It can be distinguished between non-absolute or relative orientation and absolute orientation. Absolute orientation means orientation of the sensor with respect to the earth and its magnetic field. In other words, absolute orientation sensor fusion modes calculate the direction of the magnetic north pole. In non-absolute orientation modes, the heading of the sensor can vary depending on how the sensor was placed initially.

Features:

• Magnetic Field, Acceleration and Angular Rate. The BNO055 contains a triaxial geomagnetic sensor, a triaxial 16-bit gyroscope and a triaxial 14-bit accelerometer in a single package. This enables you to simultaneously measure the linear acceleration, rotational acceleration and the strength of the magnetic field. 
• Fusion Modes. The fusion algorithm running on the on-board 32-bit microcontroller reads all the sensors simultaneously and delivers extremely valuable data like the gravity field vector, the device's absolute orientation (through the quaternions and euler vectors), the magnetic north (as with a compass), etc.
• 3.3V and 5V Power Supply. The on-board voltage regulator accepts anything from 2.6V to 5.5V to supply the BME280 sensor. 
• I2C Communication. Using the I2C protocol you need no more than two wires to communicate with the BNO055 sensor.
• Data Transfer with both 5V and 3.3V devices. While devices like the Arduino Uno interpret a 5V signal as a logic HIGH, the BNO055 uses 3.3V as a logic HIGH. The on-board logic level converter translates the 5V signals into 3.3V signals and vice-versa.
