Introduction

The BNO055 smart sensor board is a compact board that provides a triaxial 14-bit accelerometer, an accurate close-loop triaxial 16-bit gyroscope, a triaxial geomagnetic sensor and a 32-bit microcontroller running the BSX3.0 Fusion software. By integrating sensors and sensor fusion in a single device, the BNO055 makes integration easy, avoids complex multivendor solutions and thus simplifies innovations such as novel applications for IoT hardware. The BNO055 is the perfect choice for AR, immersive gaming, personal health and fitness, indoor navigation and any other application requiring context awareness. It is ideally suited for demanding applications such as augmented reality, navigation, gaming, robotics, or industrial applications.

Data Output

The BNO055 can output the following sensor data:

• Absolute Orientation (Euler Vector, 100Hz)
  Three axis orientation data based on a 360° sphere

• Absolute Orientation (Quaterion, 100Hz)
  Four-point quaternion output for more accurate data manipulation

• Angular Velocity Vector (100Hz)
  Three axis of ‘rotation speed’ in rad/s

• Acceleration Vector (100Hz)

Hardware Board and Case Diagram

Connecting using the I2C

I2C uses only two wires; SCL and SDA. The sensor board can be interfaced using these two wires only as depicted in this figure. Make sure to connect VCC and GND of the board to a source of 5V and GND.

If used with the NB-IOT board as below, connect the SCL, SDA, GND, VCC lines in the two boards together.

Working with Arduino

The sensor board can work with the 5G NB-IoT board or any other Arduino board. Simply connect VCC and GND to the sensor board and wire the two I2C wires between the Arduino board and sensor board. Run Arduino sketch, and you will see all readings from the BNO055 sensor module.

The following shows the Arduino sketch for BNO055 sensor board running and displaying temperature, Gyroscope, Magnetometer, Accelerometer readings.
