Description

Technical Field

[0001] The utility model relates to the technical field of air quality monitoring, in particular to an air quality monitoring device. Background Art

[0002] As people's health awareness continues to improve, they are paying more and more attention to air quality. Air quality monitoring equipment is a device used to measure and monitor the content of various pollutants in the air, and now it is widely available around people.

[0003] Existing commercial-grade indoor air quality monitoring equipment requires multiple sensors to be built in, as multiple air parameters need to be monitored simultaneously. This creates space constraints, hinders ventilation and heat dissipation, and results in poor measurement accuracy. The need to display multiple monitoring values ​​simultaneously results in a larger display screen and increases internal heat generation within the monitoring equipment. Furthermore, to facilitate the use of the monitoring equipment and meet a wider range of scenarios, multiple data communication interfaces and power supply options are required for uploading data. These requirements result in high internal heat generation while also requiring high measurement accuracy. Air quality monitoring equipment is also a long-term online monitoring device, requiring wall mounting. This requires both accurate measurement values ​​and easy installation without affecting the aesthetics of the building space, while also enabling real-time viewing of monitoring data.

[0004] Therefore, it is hoped that there will be a new air quality monitoring device that can overcome the above problems. Utility Model Content
