Description

Technical Field

[0001] The utility model relates to the technical field of temperature and humidity sensors, in particular to a contact type temperature and humidity sensor. Background Art

[0002] A temperature and humidity sensor is a device used to measure ambient temperature and humidity. Typically consisting of a temperature sensor and a humidity sensor, it accurately measures ambient temperature and humidity and transmits this data to a monitoring system or controller. These sensors are widely used in areas such as indoor climate control, greenhouse monitoring, warehouse management, medical equipment, and industrial automation. The precise measurement capabilities of temperature and humidity sensors are crucial for many industries, helping users better understand and control environmental conditions, thereby improving production efficiency and product quality.

[0003] The existing contact temperature and humidity sensor measures temperature and humidity during the contact process. After each detection, the outer surface of the probe is extremely easy to stick to the object to be measured. If it is not cleaned in time, the object to be measured will adhere to the outer surface of the probe. Over time, the outer surface of the probe will have more impurities or even form a layer of impurity structure, thereby affecting the detection accuracy. Therefore, it is necessary to improve the existing temperature and humidity sensors. Therefore, the utility model proposes a contact temperature and humidity sensor. Utility Model Content
