That is correct, you will need to know the supply voltage to calculate the resistance. However, the voltage read by the ADC is not supply dependant.Should be replaced with
Thank you very much! so once i've calculated Vout
Vout = ADC_Value * 0.0001875;
i can use it in the formula
Rth + 10k = VCC * 10k / Vout
to calculate resistence and then use this
Temperature(in kelvin) = 1 / (A + B[ln(Rth)] + C[ln(Rth)]^3)
to get temperature?
