Why measure carbon dioxide?

As we said, carbon dioxide at room temperature is a colorless, odorless gas that cannot be detected by the senses. Low concentrations of carbon dioxide are not toxic, while high concentrations can poison animals. In addition, carbon dioxide is very harmful to the environment and is the main cause of the greenhouse effect. After absorbing the long-wave radiation on the ground, greenhouse gases such as carbon dioxide in the atmosphere can radiate longer-wavelength long-wave radiation to the ground, which has the effect of heat preservation on the ground. When the temperature continues to rise, it leads to global warming. In addition, human activities will emit a large amount of carbon dioxide, leading to a sharp increase in the concentration of greenhouse gases in the atmosphere, which will lead to the intensification of the greenhouse effect. By measuring the amount of carbon dioxide (CO2) in the environment, timely actions and preventive measures can be taken to reduce the concentration of CO2 in the atmosphere. In agriculture, carbon dioxide is one of the raw materials used by green plants for photosynthesis, which accounts for 95 percent of the dry weight of crops. Therefore, the use of carbon dioxide sensors to control concentration has become an important factor affecting crop yield. For example, in greenhouse planting, the level of carbon dioxide concentration can affect the quality of crop growth. Industrially, solid carbon dioxide is commonly used to refrigerate frozen foods and other perishable foods in transit, and as a refrigerant in many industrial processes. Gaseous carbon dioxide is commonly used in carbonated beverages, water treatment processes for pH control. In the medical industry, it is also used as a diluent for bactericidal gases. All this requires measuring carbon dioxide (CO2). We can use CO2 sensors for online monitoring.
