NTC Calculator

Characterise the NTC thermistor using the Beta method.

$$r_{\infty} = R_{25} \cdot exp \left(\frac{-B}{T_{25}}\right)$$

Calculate the thermistor resistance from voltage and then use this to calculate temperature

$$R = \frac{V_{out} \cdot R_2}{V_{cc} - V_{out}}$$

$$T = \frac{B}{\ln(R/r_{\infty})}$$
