Description

Technical Field

[0002] Carbon dioxide emissions monitoring refers to the process of monitoring and analyzing the concentration of carbon dioxide in the atmosphere. By monitoring the concentration of atmospheric carbon dioxide around the world, scientists can understand the source, distribution and trend of carbon dioxide emissions, and thus assess the impact of climate change and human activities on the earth. Carbon dioxide emissions monitoring is crucial for climate change research and environmental protection. It can provide a scientific basis for governments and international organizations to formulate relevant policies, and it can also help companies and individuals understand their own carbon emissions and take corresponding emission reduction measures.

[0003] However, the traditional carbon dioxide emission monitoring equipment currently on the market uses a carbon dioxide detector to detect carbon dioxide content. It uses the infrared principle to continuously detect carbon dioxide emissions through the absorption characteristics of carbon dioxide under infrared light. However, due to the characteristics of infrared rays themselves, water vapor in the gas will cause refraction and scattering of infrared rays, and the detection accuracy of the infrared carbon dioxide detector will be affected by humidity.
