Acceleration Sensor BMA455
BMA455
Accelerometer
The ultra-small, triaxial BMA455 is a low-g high performance acceleration sensor with digital interfaces. BMA455 is aiming for low-power and demanding consumer electronics applications and extends battery lifetime by its low current consumption. The accelerator is able to detect significant motion and tilt. Furthermore, BMA455 enables plug ’n’ play step counting in smartphones and wearable devices. The accelerator is optimized to fulfill Android™ N low-power accelerometer requirements and integrates Android 6.0 “Marshmallow” features that minimize programming effort.
