Sıcaklık Sensörü Probu (DS18B20 ve PT100'ün Fonksiyonel Devre Tasarımı)
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;
