The Development Status of Temperature Sensors

In recent years, the process of industrial modernization and the continuous high-speed growth of the electronic information industry in China have driven the rapid rise of the sensor market. Temperature sensors, as an important type of sensor, account for over 40% of the total demand for sensors. A temperature sensor is a semiconductor device that utilizes the temperature dependent resistance of NTC to convert non electrical physical quantities into electrical quantities, enabling precise temperature measurement and automatic control. Temperature sensors have a wide range of applications, including temperature measurement and control, temperature compensation, flow rate, flow and wind speed measurement, liquid level indication, temperature measurement, ultraviolet and infrared light measurement, microwave power measurement, etc. They are widely used in fields such as color TVs, computer color displays, switching power supplies, water heaters, refrigerators, kitchen equipment, air conditioners, and automobiles. In recent years, the rapid growth of the automotive electronics and consumer electronics industries has driven the rapid increase in demand for temperature sensors in China.
