Thermistor temperature sensor principle

　　Thermistor is a category of sensitive components. According to different temperature coefficients, it is divided into a positive temperature coefficient thermistor (PTC) and negative temperature coefficient thermistor (NTC). The typical feature of thermistor is sensitive to temperature, and different resistance values are shown at different temperatures. The higher the temperature coefficient thermistor (PTC) when the temperature is higher, the greater the resistance value, and the lower the temperature coefficient thermistor (NTC) when the temperature is higher, the lower the resistance value, and they belong to the semiconductor device.

　　Thermal resistance is a type of thermal resistance, so the principle is that the temperature causes resistance. At present, there are two types of metal thermal resistance and semiconductor heat -sensitive resistance.
