# Thermistor calculation

Let’s consider the following divider bridge. The high side is a resistor and the low side is a thermistor.

The resistance of the thermistor can be calculated with the following formula:

$R = R_0 . \exp ( \beta. ( \frac {1}{T+273.15} - \frac {1}{T_0+273.15} ) )$

Where :

• $T_0$ is the reference temperature [°C]
• $T$ is the target temperature [°C]
• $\beta$ is the thermistor Beta Value [K]
• $R_0$ is the resistance at reference temperature [Ohms]
