Acceleration sensor BMA280

BMA280

Accelerometer

The ultra-small BMA280 is an advanced, triaxial, low-g acceleration sensor with digital interfaces, aiming for low-power consumer electronics applications. It senses tilt, motion, shock and vibration e.g. in cellular phones, man-machine interfaces, VR features and game controllers. An evaluation circuitry (ASIC) converts the output of a micromechanical acceleration-sensing structure (MEMS). The BMA280 accelerometer facilitates its use especially in motion detection applications such as device orientation, gaming, HMI and menu browser control.
