Temperature sensor refers to a sensor that can sense temperature and convert it into a usable output signal. Temperature sensor is the core part of temperature measuring instruments and there are many varieties. According to the measurement method, it can be divided into two categories: contact type and non-contact type. According to the sensor material and electronic component characteristics, it can be divided into two categories: thermal resistor and thermocouple.
