Comparação entre a sonda do sensor de temperatura PT100 e o módulo DS18B20
1) Princípio básico de aquisição de sinal
① A resistência do PT100 muda proporcionalmente com a temperatura (quanto maior a temperatura, quanto maior a resistência), mas a mudança de resistência é muito pequena, sobre 0.385 Oh / grau;

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.

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.
