BMI055
The BMI055 is an ultra-small, 6 axis inertial sensor, consisting of: A digital, triaxial 12bit acceleration sensor and a digital, triaxial 16bit, ±2000°/s gyroscope. The BMI055 allows very low-noise measurement of angular rates and accelerations in 3 perpendicular axes and thus senses tilt, motion, shock and vibration in cellular phones, handhelds, computer peripherals, man-machine interfaces, remote and game controllers.
With its ultra-small footprint of only 3 mm x 4.5 mm the BMI055 is unique in the class of low-noise inertial measurement units. On top, the BMI055 integrates a multitude of features that facilitate its use especially in the area of motion detection applications, such as device orientation measurement, gaming, HMI and menu browser control.
