9 axis IMU sensor replace STIM300 high accuracy MEMS inertial measurement unit with temp sensor
The MEMS inertial measurement unit consists of a three-axis gyroscope, a three-axis acceleration meter, a three-axis inclination angle, a temperature sensor, a signal processing board, a structure and necessary software, and is used for measuring three-axis angular rate, three-axis acceleration and three-axis inclination angle of a carrier. And output that gyro, the loading table and the inclination data aft error compensation (including temperature compensation, installation misalignment angle compensation, nonlinear compensation and the like) through an RS-422 serial port according to an agreed communication protocol.
