Sondă cu senzor de temperatură (Proiectarea circuitelor funcționale ale DS18B20 și PT100)
Comparison between PT100 temperature sensor probe and DS18B20 module
1) Basic principle of signal acquisition
① The resistance of PT100 changes proportionally with the temperature (the higher the temperature, the greater the resistance), but the resistance change is very small, about 0.385 Ω / degree;
