Bosch Sensortec


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.
