Какво е DS18B20 температурен сензор?
NTC (отрицателен температурен коефициент) temperature sensor is a temperature measuring element that uses the exponential decrease in the resistance of a thermistor as the temperature rises. Its core is a ceramic semiconductor made by sintering metal oxides (such as manganese, cobalt, and nickel), and the temperature is inferred by measuring the change in resistance. The following are its core technical characteristics, приложения, and selection points:
