10.3.5 Converting (internal) air temperature (T-air)

This section describes how to convert raw values from a KTY 82 air temperature sensor to ºC. The
temperature in raw values can be read from register 0x4B.
In the following description, the actual temperature read in units is called Actual_temp_raw.
The following data is needed for the conversion (Temperature is in ºC):

When converting a temperature given in raw values to centigrade, the interval i must be found. Select
the first interval (table row) where the Raw_value is smaller than the Actual_temp_raw.
