There are accelerometers, gyroscopes, and magnetometers in the IMU. By fixing the imu to the object, you can obtain some information about the object during its movement, such as the object's three-axis acceleration information, three-axis angular velocity information, and three-axis angle information. , three-axis magnetic field information. Through this information, the state of the object during motion can be known.
IMU design has a wide range of applications and plays an important role in military aerospace, navigation, military, medical, entertainment, robotics, vehicles and other fields.
There are 3 product models in total:
- A9: Three-axis acceleration information, three-axis angular velocity information, three-axis angle information, and three-axis magnetic field information can be obtained.
- B9: Three-axis acceleration information, three-axis angular velocity information, three-axis angle information, and three-axis magnetic field information can be obtained.
- B6：Three-axis acceleration information, three-axis angular velocity information, and three-axis angle information can be obtained.
