FSS-IMUP9
IMUP9 is a MEMS inertial measurement unit (IMU) with 6 degrees of freedom (DOF) developed by Forsense (Shanghai) Technology Co., Ltd. It features three_axis gyroscopes and three_axis accelerometers, measuring angular velocity and linear acceleration respectively.
High precision and high resolution combine to help capture subtle vibration and tilt. A large number of output parameters enable the perception of motion despite intense shaking. All IMU modules are calibrated independently on a rotary table and adjusted precisely over an ultra_wide temperature range in a temperature chamber before leaving the factory, so that they can deliver stable and consistent performance in most extreme conditions.
