CH104
CH104 integrates a 3-axis accelerometer, a 3-axis gyroscope, a 3-axis magnetometer, and a microprocessor. It is an inertial measurement unit (IMU) that can simultaneously output the 3-axis angular velocity, 3-axis acceleration, 3-axis magnetic field, quaternion and Euler angle after sensor fusing. You can tune the IMU to fit your application, for example, change sampling rate and sensor fusion mode (6-axis or 9 axis). CH104 brings more possibilities to robots, unmanned driving, and AR/VR, or automation machine.
Sensor fusion + IMU array technique
CH104 uses the exclusive data fusion algorithm (integreted IMU array technique). The high-performance raw data and the Euler angle and quaternion after sensor fusion have very small data delay and phase distortion (less than 2.5ms). We provide ANROT IMU GUI software to help you quickly evaluate and test.
