To estimate the error, we calculate the highest possible measured voltage at \SI{60}{\celsius}.
According to the design of the voltage divider, the lower the temperature, the higher the output voltage.
As shown in Fig. \ref{fig:vref2}, the supply voltage $V_{REF2}$ for the voltage divider can reach a maximum value of \SI{3.006}\volt.
As shown in Fig. \ref{fig:vref}, the supply voltage $V_{REF2}$ for the voltage divider can reach a maximum value of \SI{3.006}\volt.
Additionally, the total measurement error of the GPIO is $\pm\SI{0.0028}{\volt}$ (as shown in Fig. \ref{fig:aux}).
Lastly, the maximum resistance of the NTC at \SI{60}{\celsius}, according to the LUT (Tab. \ref{tab:lut}), is \SI{3086.8}{\ohm}.
The maximum possible voltage measurement can then be calculated as such:
