In this tutorial, we learn how to interfacing Thermistor with an Arduino. How to get temperature readings from Thermistor and display them in LCD Display.

A thermistor is also known as a thermal resistor that is used to sensing temperature like cold and heat around us. The thermistor is a resistor whose resistor is changed according to change in temperature.

Thermistors are cheap, reliable and respond quickly. They are mainly used for low-temperature range but not for high temperatures.

Thermistors are mainly used in home appliances, for circuit protections, refrigerator, etc.
