Product Details
Accelerometer
• Chip: BMA423
• Latest generation triaxial, low-g acceleration sensor from Bosch
• ultra-small
• digital interfaces
• 2 bit digital resolution and embedded intelligence,
• allows low-noise measurement of accelerations in 3 perpendicular and thus senses wrist
tilt, tab/double tab and enables plug ’n’ play step counting especially in wearable devices.
Recommended for
- 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
