Thermistors or as we called sensor in Refrigeration and air conditioning unit. what are they? Let’s start by breaking down their name, which will give us a pretty clear indication of what they are and what they do: thermistor = thermal resistor. They are small electronic devices that react to a change in temperature (ambient included) by changing their resistance value.
How do they do this? Well, there are two main types of thermistors: NTC and PTC. Each is made of a different material that reacts to temperature in a specific way.
NTC - negative temperature coefficient
PTC- positive temperature coefficient
