Interpreting sensor names
Here is the output from the sensors command on my Late 2012 MacMini 6,2 running Linux. I am unable to find out what each code means. What parameter do each of these code represent?
I would like to set configuration parameters in a utility caled macfanctld. According to the manpage of macfanctld, I can exclude sensors by their number. I am assuming that sensor 1 is TA0P, sensor 2 is TA0p and so on. Am I wrong? The man page also mentions that the individual parameters can be fine tuned, but does not mention how. How I can assign less weight to a particular sensor?

I've found this page (archived) explaining vast majority of SMC keys.
As for your question, I believe that TA0P and TA0p is the same thing. A0 means ambient sensor #0 and p means proximity.
TC-- are sensors for CPU/logic board.
Latest D means CPU die (sensor), and H refers to heatsink.
