Product Description
The IMU6 inertial measurement unit consists of three-axis gyroscope, three-axis accelerometer, three-axis tilt angle (without this sensor by default), temperature sensor, signal processing board, structure and necessary software, and is used to measure the three-axis angular rate, the three-axis acceleration and the three-axis tilt angle of the carrier. And output the gyro, accelerometer and the inclination data after error compensation (including temperature compensation, installation misalignment angle compensation, nonlinear compensation and etc) through RS-422 serial port according to an agreed communication protocol.
