The role of inclination sensors in sports training is multifaceted, providing precise movement data. Bluetooth sensors are particularly suitable for testing subtle and frequent dynamic changes in motion.

Inclination sensors are devices used to detect and measure the orientation or position of objects in three-dimensional space. They typically employ various sensor technologies, such as accelerometers, gyroscopes, and magnetometers, to capture direction, rotational angles, and location information. By monitoring and recording the object‘s posture in real time, inclination sensors aid in achieving precise navigation, motion control, and posture analysis.

Inclination sensors leverage Micro-Electro-Mechanical System (MEMS) technology, integrating a triaxial gyroscope, triaxial accelerometer, and triaxial electronic compass among other motion sensors. These components output calibrated angular velocity, acceleration, and magnetic data through an embedded low-power ARM processor. After processing with a quaternion-based sensor data algorithm, they can provide zero-drift three-dimensional posture data represented in quaternions or Euler angles in real time.

With features like trajectory record, real-time changes in motion angles, and portability, these sensors assist athletes and coaches in analyzing technical movements and optimizing training outcomes. Here are some applications:
