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.

The example values above (for illustration only, the given combination will not occur in reality)
are combined to the register value 0x5307 = 21255.
The single status are retrieved from the register as integer part of
Status 1 = register / 4096
Status 2 = ( register / 256 ) AND 0x000F
Status 3 = ( register / 16 ) AND 0x000F
Status 4 = register AND 0x000F
Following table shows the status coding:
