Design Description This temperature sensing circuit uses a resistor in series with a negative-temperature-coefficient (NTC) thermistor to form a voltage divider, which has the effect of producing an output voltage that is linear over temperature. The circuit uses an op amp in a non-inverting configuration with inverting reference to NTC thermistor circuit. The simplest circuit to measure temperature with a thermistor is to use the thermistor as part of a resistor divider circuit, as shown in Figure 1. Figure 1. NTC Thermistor Circuit. In this circuit, the NTC thermistor and the resistor form a voltage divider network. As the temperature changes, the resistance of the NTC

A Basic Thermistor Circuit. Let's build a basic thermistor circuit to see how it works, so you can apply it to other projects later. Since the thermistor is a variable resistor, we'll need to measure the resistance before we can calculate the temperature. However, the Arduino can't measure resistance directly, it can only measure voltage.
