Precision air conditioning has the characteristics of high efficiency, stability, accuracy and safety, which can ensure the quality and efficiency of the production process, while also extending the life of the equipment and reducing energy consumption. It is one of the important equipment indispensable for modern industrial production. Precision air conditioning temperature and humidity sensor is a device used to measure ambient temperature and humidity. Temperature sensors can use a variety of technologies, such as thermocouples, thermistors or semiconductor temperature sensors. Humidity sensors are used to measure the humidity level in the environment. The most common humidity sensors are humidity sensors based on the principle of capacitance. They use the hygroscopic properties of the material to measure humidity and convert humidity into electrical signals. Such sensors are usually integrated with temperature sensors to provide accurate temperature and humidity measurements.

[0003] Temperature and humidity sensors are usually installed inside precision air conditioners. Existing temperature and humidity sensors are close to precision air conditioners, and the temperature near the precision air conditioners is somewhat different from the ambient temperature and humidity, which can easily lead to a certain deviation between the temperature and humidity adjustment of the precision air conditioners and the required temperature and humidity.
