[0002] A temperature sensor is a sensor that can sense temperature and convert it into a usable output signal. Temperature sensors are the core part of temperature measuring instruments and come in many varieties. According to the measurement method, they can be divided into two categories: contact and non-contact. According to the sensor material and electronic component characteristics, they can be divided into two categories: thermal resistors and thermocouples. The use principle of common temperature sensors is to use resistance sensing to achieve temperature sensing. As the temperature changes, the resistance value of the metal also changes, and the resistance value can be directly used as an output signal.
