Make an Arduino Temperature Sensor Thermistor Tutorial SIN Circuit Diagram A thermistor exhibits resistance with higher sensitivity to temperature compared to other types of resistors. Using an Arduino, we can measure and process the thermistor's readings and then convert them into more common temperature units.
Thermistors vs. RTDs As discussed in the article " How to Select and Design the Best RTD Temperature Sensing System," an RTD is a type of resistor with resistance that varies as a function of temperature. Thermistors operate in a similar manner to RTDs.

In addition to the evaluation board, TI also has a downloadable Thermistor Design Tool which offers complete resistance vs. temperature table (R-T table) computation, other helpful methods to derive temperature, and example C-code. Conclusion Thermistors are widely used, easy to connect, versatile sensors for measuring temperature.
A thermistor is a thermal resistor - a resistor that changes its resistance with temperature. Technically, all resistors are thermistors - their resistance changes slightly with temperature - but the change is usually very very small and difficult to measure. Thermistors are made so that the resistance changes drastically with temperature so that it can be 100 ohms or more of change per degree
How to Measure Temperature with an NTC Thermistor Circuit Diagram
Design Notes: For temperature sensing using an NTC thermistor, the resistor, R1, is chosen based on the temperature range and the NTC's value.
