It's a simple way to make it easy for the webapp author to find out if the global thermal state of the system is normal, or getting near dangerous levels. The author then doesn't need to perform hardware-dependent calculations to try and average out the different temperatures reported by the system: you can't really provide a single temperature for the system, since you can have many thermometers reporting values collected at different locations in your system. > Also, are you assuming that > > currentTemperature = min + state * (max - min) > > (i.e., you interpolate in a linear fashion, as opposed to having, > say, state^2 up there)? No, I'm not assuming any relationship between current temperatures and the general thermal state. It's left to the API implementation. > Editorial: > > s/Celcius/Celsius/g Fixed, thanks. Max.
