BMA421规格书详情
描述 Description
The BMA421 is an ultra-small, triaxial, low-g acceleration sensor with digital interfaces, aiming for low-power consumer electronics applications. Featuring 12 bit digital resolution and embedded intelligence, the BMA421 allows low-noise measurement of accelerations in 3 perpendicular axes and thus senses any-motion/no-motion and enables plug ’n’ play step counting in smart phones and wearable devices. Furthermore the device is optimized to fulfill low power step counter requirements.
应用 Application
- Step-counting in smartphones
- Step-counting in wearable devices
- Low power user interaction
- Gesture recognition
- Advanced power management for mobile devices
- Tilt compensation for electronic compass
