What is DS18B20 Temperature Sensor?
NTC (ujemny współczynnik temperaturowy) 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, i nikiel), and the temperature is inferred by measuring the change in resistance. The following are its core technical characteristics, aplikacje, and selection points:
