Stim300 IMU Accelerometer Gyro Sensor High Accuracy Factory Supply
Product Description
This instruction manual is the main reference document for the use and operation of IMU6-1, and is mainly prepared in accordance with the Technical Agreement of IMU6-1 MEMS Inertial Measurement Unit and the Technical Conditions of Inertial Measurement Unit and Triaxial Gyro Combination. IMU6-1 series inertial measurement unit can change the measurement accuracy and measurement range of the inertial sensor according to the user's requirements.
Composition and function 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.
