Three-in-one nine-axis system-in-package absolute orientation sensor

11-02-2015 | Mouser Electronics | Test & Measurement

Mouser is now stocking the BNO055 intelligent nine-axis absolute orientation sensor from Bosch Sensortec. The system-in-package (SiP) solution integrates a 32-bit ARM Cortex M0+ microcontroller running Bosch Sensortec sensor fusion software, along with three sensors – a triaxial 14-bit accelerometer, a triaxial 16-bit gyroscope with a range of ±2,000 degrees per second and a triaxial geomagnetic sensor – in a single miniature package. The integrated sensor fusion software helps developers reduce development costs and time, while the integrated components in one package leads to simplified system integration and faster time to market. The BNO055 is the first in a new family of application-specific sensor nodes (ASSN). An integral part of the BNO055 product offering is the BSX3.0 FusionLib software, which ensures optimal system performance and eliminates the need for third-party software. The hardware and software of the BNO055 enables high performance with low power consumption, and helps free developers from the complexities of multivendor solutions or additional software requirements. Other features include fast background calibration of all sensors and the calibration monitor while in use, enhanced magnetic distortion detection and suppression, built-in group delay compensation for real-time motion tracking, gyroscope drift cancellation, and support for multiple power modes and multiple operating modes (i.e. for 6-axis-based applications, such as inertial measurement units). The BNO055 is also equipped with digital bi-directional I2C and UART interfaces. The I2C interface can be programmed to run with the HID- I2C protocol, turning the BNO055 into a plug-and-play sensor hub solution – ideal for devices running the Windows 8.0 or 8.1 operating system, says the company. Typical applications include augmented reality, immersive gaming, personal health and fitness, indoor navigation and any other sensor-based applications requiring context awareness. The BNO055 is also supported by the 262-0330.SBO.184 multi-function development tool, says the company.
