BMA456

Accelerometer

The BMA456 is an ultra-small, triaxial, low-g high performance acceleration sensor with digital interfaces. The sensor is suitable for low-power and demanding consumer electronics applications. It detects wrist tilt, tab/double tab and enables plug ’n’ play step counting especially in wearable devices.
