Description

technical field [0001] The invention relates to a device for measuring air pollution. Background technique [0002] Carbon dioxide is a common compound in the air, its molecular formula is CO2, it is a colorless and odorless gas at room temperature, its density is slightly higher than that of air, and it can dissolve in water. It is the main source of the greenhouse effect. A small amount of carbon dioxide is not harmful to the human body, but an excessive amount will affect human breathing, increase blood carbonic acid, and cause acidosis. [0003] The molecular structure of carbon dioxide is very stable, and its chemical properties are inactive. At present, there are infrared absorption method, chemical method, electrochemical method, and gas chromatography method for measuring carbon dioxide. The disadvantages of this method are high cost, poor universality, complex algorithm, and large equipment volume. Wait. Contents of the invention [0004] In order to solve the d...
