    A: Hi Arthur, Unfortunately it isn’t possible to program the thermistor, the resistance would alter as the temperature changes and you would use a micro controller to detect the change and program this to change the output depending on the current resistance.

How A Thermistor Works
A guide to understanding how a thermistor works. A thermistor is a component that has a resistance that changes with temperature. There are two types of thermistor. Those with a resistance that increase with temperature (Positive Temperature Coefficient – PTC) and those with a resistance that falls with temperature (Negative Temperature Coefficient – NTC).
