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

Package includes:
