_API”).

The microcontroller sends a start sequence to start a pressure or temperature measurement. After

converting time, the result value (UP or UT, respectively) can be read via the interface. For

calculating temperature in °C and pressure in hPa, the calibration data has to be used. These

The sampling rate can be increased up to 128 samples per second (standard mode) for dynamic

measurement. In this case, it is sufficient to measure the temperature only once per second and to

use this value for all pressure measurements during the same period.
