[0024] In practical applications, temperature sensors are existing technologies. Temperature sensors refer to sensors that can sense temperature and convert it into usable output signals. They can be divided into two categories: contact and non-contact according to the measurement method, and into thermal resistors and thermocouples according to the characteristics of sensor materials and electronic components.
