What is a Surface temperature sensor?

The application of the surface temperature sensor differs between contact and non-contact types. A typical contact-type surface temperature sensor, the "thermocouple," is used to bring the thermocouple into contact with the object whose temperature is to be measured, and is mainly used for research and testing. Another contact-type surface temperature sensor is the "thermistor," which is widely used in electrical appliances such as refrigerators and air conditioners, and can be said to be the most mass-produced surface temperature sensor. Next, with regard to temperature measurement using a "sensor that detects the amount of infrared rays," which can be said to be representative of non-contact surface temperature sensors, it is possible to measure temperature without touching the object. used in the scene.
