    BHA250

    The BHA250 is a small, low power smart-hub with an integrated three axis accelerometer plus a programmable microcontroller. Containing pre-installed software and specific algorithms for activity recognition, it is specifically designed to enable always-on motion sensing. It perfectly matches the requirements of smartphones, wearables or any other application which demands highly accurate, real-time motion data at a very low power consumption level. The device integrates our millionfold proven 14 bit 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 on-board memory the BHA250 offers a low power solution for motion sensing and data processing. Software included! Programmable! Extendable!

    Applications

    - Activity recognition of standing, walking, running, biking or in vehicle

    - Step-counting, Indoor navigation and PDR

    - HMI interfaces incl. gesture detection of motion, tilt, pickup, wake up, glance or other gestures for wearables

    - Augmented reality and immersive gaming

    - Tilt compensated eCompass and orientation

     
     

    Mobile Applications

    Would you like to check an altitude on a map and plan the the best route or check the local weather forecast for your next hike? Are you monitoring your daily sports acitivities with your smartphone? These and many more outdoor applications are enabled by MEMS sensors. These new and advanced devices will even help you to find your car in a public parking garage.
