BHA260AB

Programmable smart sensor combining accelerometer and fusion software

The BHA260AB is a smart sensor, which is optimized for 24/7, always-on sensor processing at ultra-low power consumption. BHA260AB consists of the new custom programmable and powerful 32-bit microcontroller, a 3-axis accelerometer and a powerful software framework containing pre-installed sensor fusion and other sensor processing software. In combination with its wide connectivity and extendibility, the BHA260AB becomes a versatile and ideal solution when it comes to applications such as power management and wake-up control, 3D orientation, step counting or activity recognition in smartphones, wearables and other mobile devices.

This includes algorithms for offset calibration of each sensor, monitoring of the calibration status and Kalman filter fusion to provide distortion-free and refined orientation vectors. Since Bosch Sensortec 9-axis fusion software is developed together with the sensor hardware, optimized performance in terms of dynamics and immunity to distortion effects is achieved. Direct access to the Bosch sensor hardware allows the user to set use case specific operation modes regarding data rates and noise thresholds. The solution provides a ready-to-use advanced 9-axis sensor fusion system which reduces the complexity for customers and helps in rapid development of advanced sensor applications.
