This tutorial will introduce methods for relating resistance to temperature by fitting factory calibration data. An NTC 3950 100k thermistor will be used, which is designed for 100kOhm resistance at 25 degrees Celsius. NTC thermistors are most common in commercial products that operate in the tens of degrees like thermostats, toasters, and even 3-D printers. In our case, we will be using a Negative Temperature Coefficient (NTC) thermistor, where the resistance decreases as the temperature increases. For most applications, thermistors are the smart and easy selection for temperature sensing below 300 degrees Celsius. Thermistors are often chosen over thermocouples because they are more accurate, have a shorter response time, and are generally cheaper. Thermistor, whose name is derived from a combination of thermal and res istor, is a temperature sensing device that registers changes in internal resistance as a function of temperature.
