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 ‘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
– Tilt compensation for electronic compass
