9 axis IMU sensor replace STIM300 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.
