Description

Technical Field

[0001] The utility model relates to the technical field of temperature, humidity and air pressure sensors, in particular to a shutter box type sensor for measuring air temperature, humidity and air pressure. Background Art

[0002] The louvered box type temperature, humidity and pressure sensor is a fully digital detection, high-precision sensor, which is integrated with high-precision digital temperature, humidity and pressure. It can accurately and quickly detect atmospheric temperature, atmospheric humidity and atmospheric pressure. The built-in signal processing unit can output corresponding signals according to user needs. The high-strength structural design can accurately detect in harsh climate environments. It can be widely used in meteorology, ocean, environment, airports, ports, laboratories, industry, agriculture and transportation. The louvered box type temperature, humidity and pressure sensor has a small blade gap in the design, which helps to protect the sensitive components inside from direct wind and sun.

[0003] However, it still has the following disadvantages in actual use:

[0004] Since these sensors are usually installed in outdoor environments for a long time, dust and other tiny particles may accumulate and clog the tiny gaps between the blades over time. Dust will hinder air flow and reduce the sensor's response speed to changes in temperature, humidity and air pressure, thereby reducing its detection sensitivity and affecting data accuracy and reliability, which in turn increases maintenance costs. Long-term dust accumulation will also damage the internal structure of the sensor, shortening its lifespan. Utility Model Content
