Bosch Sensortec – BNO055

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 12-bit accelerometer, a triaxial 16-bit gyroscope with a range of ±2000 degrees per second, a triaxial geomagnetic sensor and a 32-bit microcontroller running the company’s BSX3.0 FusionLib software. At just 5.2 x 3.8 x 1.1 mm³, it is significantly smaller than comparable discrete or system-on-board solutions.

By integrating sensors and sensor fusion in a single device, the BNO055 eases the integration process for customers, freeing them from the complexities of multi-vendor 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.
