The AtMega168 and AtMega328 both support an internal temperature sensor on analog
port 8 (there's no input pin for this, it's purely internal). Using the internal temperature sen-
sor requires you to also use the internal 1.1v reference (you will still benefit from connect-
ing AVREF to GND using a capacitor (e.g. 100nF))
You can read the current raw temperature conversion voltages using, for example:
50 $C8 analogDemo <exe>
But we can convert this directly to a temperature. The AtMega328 Manual, section 24.7
says:
Rearranging, this becomes:
And Vin in mV is related to the temperature according to:
