+There are many circuits and measurement methods that can be used with a thermistor to determine the temperature. The simplest approach is to use a half-bridge circuit also known as a resistor divider, shown in Figure 1. The goal is to perform a ratiometric measurement such that the VREF source voltage to the divider is the same as the reference to the ADC used to measure the voltage at VT. The R1 resistance is known.
