Sensor Status:
Each register hoIds 4 sensor status coded with 4 bits per status. The sequence defined in
the table above is to understand as from most significant half byte to least significant half
byte. Most of the sensors have two status values, one for the sensor itself and the current
measurement value, another one for the buffer, from which average, min. And max values
are evaluated.
