Bosch Sensortec BNO055 – 9-Axis Sensor – Absolute Orientation Sensor

The BNO055 is the first in a new family of Application Specific Sensor Nodes (ASSN) implementing an intelligent 9-axis “Absolute Orientation Sensor”, which includes sensors and sensor fusion in a single package.

The BNO055 is a System in Package (SiP), integrating a triaxial 14-bit accelerometer, a triaxial 16-bit gyroscope with a range of ±2000 degrees per second, a triaxial geomagnetic sensor and a 32-bit microcontroller (Atmel SAM D20) running the company’s BSX3.0 FusionLib software. At just 5.2 x 3.8 x 1.1mm³, it is significantly smaller than comparable discrete or system-on-board solutions and the first all-in-one Windows® 8.1 compatible sensor hub.

By integrating sensors and sensor fusion in a single device, the BNO055 eases the integration process for customers, freeing them from the complexities of multivendor solutions so they can spend more time on product innovation, including novel applications such as wearable hardware. It is also the perfect choice for augmented reality, more immersive gaming, personal health and fitness, indoor navigation and any other application requiring context awareness.

Bosch Sensortec BNO055


  • 3-axis accelerometer (14Bit)
  • 3-axis gyroscope (16Bit)
  • 3-axis geomagnetic sensor
  • 32 bit ARM Microcontroller
  • 5.2 x 3.8 mm² footprint
  • Bosch Sensortec Sensor Data Fusion with fast magnetic calibration (optimally integrated & tuned)

BNO055 plus a RF interface (WiFi, BT, etc.) is a key block of IoT based sensing


  • Includes all sensors, sensor hub and optimized software
  • Low power consumption, supports various power modes for switching sensors on and off and algorithm modules to speed code development
  • Advanced 9-axis sensor fusion algorithms
  • Fast background calibration of all sensors and calibration monitor while in use
  • Enhanced magnetic distortion detection and suppression
  • Real-time motion tracking due to built-in group delay compensation
  • Gyroscope drift cancellation
  • Supports multiple operating mode, i.e. 6-axis based applications (inertial measurement Units)

Solution provided functionality:

  • Windows 8.1 compatible
  • High accuracy quaternion: 2-3 deg (static)
  • Low latency: 20 ms
  • Low calibration time: 2-3 s
  • Immune to magnetic distortions
  • Power consumption advantages through integration

What makes the difference?

  • Hardware and software co-design enables high performance with low power consumption
  • Quaternion communication is 10x more efficient than raw data
  • Integrated sensor fusion software reduces customer development costs and time
  • All components in one package leads to simplified system integration and faster time to market
  • Footprint is significantly reduced compared to discrete and system on board solutions
