The GY-9255 is a 9-axis MotionTracking device that combines a 3-axis gyroscope, 3-axis accelerometer, 3-axis magnetometer and a Digital motion processor. Based on the IC MPU-9255, which is the upgrade version of MPU9250. The new MPU-9255 is the company’s first generation 9-axis activity detection part, working in conjunction with the AAR™ activity detection library. The InvenSense ‘AlwaysOn’ low power sensor can detect run, walk, bike, no-motion, and sleep analysis on a wrist worn wearable device. This solution is ideal for Smart Watch, Smart Band, and Fitness Tracker applications that want to enable the next generation features for wearable products.
