Description

SSM25385-02 motion sensor has built-in MEMS three-axis accelerometer and three-axis gyroscope. Through advanced data processing method, it can effectively eliminate the influence of high-frequency vibration of wind turbine, gyroscope drift during long-term continuous motion, interference of low-frequency acceleration in motion process, and interference of three-dimensional displacement movement. Stable and reliable motion angle data is output at 200Hz refresh rate.
