The MPU-6050 module integrates a 3-axis accelerometer and a 3-axis gyroscope.
Accelerometer: Measures acceleration, including static forces like gravity and dynamic forces like movement or vibration, across the X, Y, and Z axes. In a static scenario, the Z-axis acceleration equals the gravitational force (9.8m/s^2), while ideally, X and Y-axis accelerations are zero.
Gyroscope: Detects rotational velocity (rad/s) or changes in angular position over time along the X, Y, and Z axes (roll, pitch, and yaw). This allows determination of an object’s orientation.
By combining data from both sensors, we can accurately determine the orientation of the sensor. While trigonometry can calculate roll and pitch angles using accelerometer values, yaw cannot be directly determined.
