BMA456中文资料Digital, triaxial acceleration sensor数据手册Bosch规格书

描述 Description

The BMA456 is an ultra-small, triaxial, low-g high performance acceleration sensor with digital interfaces, aiming for low-power and demanding consumer electronics applications. Featuring 16 bit digital resolution and embedded intelligence, the BMA456 allows low-noise measurement of accelerations in 3 perpen-dicular axes and thus senses wrist tilt, tab/double tab and enables plug ’n’ play step counting especially in wearable devices. The superior temperature behaviour of BMA456 facilitate accurate measurements over changing temperature. The reduced height of only 0.65 mm is beneficial for wearable devices.

应用 Application

- Step counting in wearable devices
- Wake up display on wrist tilt
- Low power user interaction by tab/double tab
- Advanced gesture recognition
- Activity recognition/tracking
- Advanced power management for mobile devices
- Tilt compensation for electronic compass
- Spirit leveling / Virtual horizon
