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;
In modern sensing technology applications, (NTC, PTC, PT100, thermocouple, thermal resistor, DS18B20, vân vân. cáp, 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

Temperature sensors are used in a wide range of fields including: industrial manufacturing, automotive applications, medical devices, HVAC systems, food processing, environmental monitoring, research and development, consumer electronics, and building infrastructure monitoring; essentially anywhere precise temperature control or monitoring is needed to ensure safety, efficiency, and optimal performance.
Thermocouples have become the industry-standard method for cost-effective measurement of a wide range of temperatures with reasonable accuracy. They are used in a variety of applications up to approximately +2500°C in boilers, máy nước nóng, ovens, and aircraft engines—to name just a few.
Both NTC temperature sensors (a type of thermistor) and thermal switches are commonly used in rice cookers to precisely monitor and control the cooking temperature of the rice by detecting the heat generated within the inner pot, allowing for consistent cooking results. NTC thermistor can get closer to the inside of rice cooker, reducing the hysteresis quality of temperature measurement.
