Review and analysis of methods of automation of temperature measurement process
Аннотация
Temperature sensing is a critical aspect in various applications, ranging from industrial processes to consumer electronics. Two commonly used temperature sensors are NTC (Negative Temperature Coefficient) thermistors and DS18B20 thermometer sensors. NTC thermistors are resistive devices characterized by a negative temperature coefficient, making their resistance decrease as temperature rises. DS18B20 sensors, on the other hand, employ a digital 1-wire interface to provide accurate temperature measurements in a wide range. Understanding the measurement and performance limits of NTC thermistors and DS18B20 sensors is vital for selecting the appropriate sensor for a given application, ensuring reliable and accurate temperature data acquisition. Implementing temperature measurements using NTC thermistors involves considering their characteristic curves, while DS18B20 sensors offer a digital output, simplifying interfacing with microcontrollers. The output from both sensors is typically in degrees Celsius, providing essential information for applications requiring precise temperature monitoring.
