Product Details:
Accelerometer:
• Chip: BMA423
• Latest generation triaxial, low-g acceleration sensor
• ultra-small
• digital interfaces
• 2-bit digital resolution and embedded intelligence
• allows low-noise measurement of accelerations in 3 perpendiculars and thus senses wrist tilt, tab/double tab and enables plug & 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
- Tilt compensation for electronic compass
