General Description
The BHA250(B) is a small, low-power smart-hub
with an integrated three axis accelerometer plus a
programmable microcontroller, all specifically
designed to enable always-on motion sensing. On
top it contains software and algorithms for motionstep-, gesture- and activity recognition. The overall
concept perfectly matches the requirements of
smartphones, wearables or any other application
which demands highly accurate, real-time motion
data at very low power consumption.
The device integrates our millionfold proven 14bit acceleration sensor with a microcontroller – the new Bosch Sensortec Fuser core. It is bringing you the full Android sensor stack inside your devices – even without having an Android OS or an Android environment. Combining this with the built in computing power and the highly configurable onboard memory the BHA smart-hub offers you a low power solution for motion sensing and data processing.
