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, semakin besar rintangan), but the resistance change is very small, mengenai 0.385 Oh / degree;
NTC temperature sensor is a thermistor sensor (Mengukur julat suhu: -30°C to +200°C (-22°F to +392°F) waterproof probe). Its resistance value changes with temperature. NTC (Pekali suhu negatif) means that its resistance value is negatively correlated with temperature, itu, as the temperature rises, the resistance value will decrease; sebaliknya, as the temperature decreases, the resistance value will increase. This characteristic makes NTC temperature sensor very suitable for measuring temperature.
In modern sensing technology applications, (NTC, PTC, PT100, Thermocouple, thermal resistor, DS18B20, dll. kabel, probe kit) temperature sensors are key measuring tools. They are widely used in industrial automation, agricultural monitoring, automobile manufacturing and other fields. In order to ensure that the temperature sensor can work stably and reliably in a humid or wet environment, waterproof and moisture-proof technology
The core technologies of sensor probes and temperature measurement cable kits involve temperature sensing, signal transmission and data processing. Temperature acquisition expert YAXUN uses high-precision Shibaura NTC thermistors for sensor temperature sensing harnesses, including sensing materials, signal processing technology, integrated design and future development trends.
