FAQ

 Answer:
The altitude calculated by the barometric sensor is generally used as a relative value over a short period. For example, taking a vertical elevator, record a height before the elevator starts, and the elevator rises to the 3rd floor, record a height, and the height difference between the two heights is accurate.

If it needs to be used in absolute occasions, you can input the height of the current position as the initial value of the calculation, and then the movement observation height change is accurate. However, if the time is long, it is also prone to the problem of height drift.

If the project requires the acquisition of accurate altitude values for a long time and the frequency requirements are high, it is necessary to integrate other sensors for processing, such as GPS.
