At present, with the development of facility agriculture, the monitoring needs of various environments in greenhouses are getting higher and higher. Meteorological environmental monitoring instruments such as carbon dioxide detectors have emerged in this context, playing an important auxiliary guidance in actual production. effect. Different from other environmental parameters, the parameter of carbon dioxide is very special. It is an important raw material for photosynthesis of plants and a product of respiration. The concentration of CO2 is closely related to the growth, development and energy exchange of green plants. The impact of agricultural production is particularly evident. In order to exert the effect of increasing carbon dioxide production, the use of carbon dioxide detectors for scientific monitoring and precise regulation is an important means of high-quality and high-yield crop agricultural crops. Most of the crops grown in greenhouses are in a closed environment. Using carbon dioxide detectors, it is found that at night, CO2 concentration increases rapidly due to the respiration of crops. At sunrise, crop photosynthesis is strengthened and CO2 concentration drops sharply. Too high or too low CO2 concentration has become an important obstacle to crop growth. Therefore, in order to avoid planting risks and increase the yield and quality of greenhouse cultivation, it is necessary to use carbon dioxide detectors to strengthen the monitoring of greenhouse carbon dioxide levels. According to the monitoring results, measures are taken to regulate and create a comfortable environment for crop growth and achieve the goal of high quality production. The use of science and technology to improve the productivity of agriculture is an unshakable goal of current agricultural development and an important guiding ideology in agricultural production. Meteorological environmental instruments such as carbon dioxide detectors have been put into use in facility agriculture, which has further improved the scientific and technological level of facility agriculture, and has also greatly enhanced the core competitiveness of modern agriculture, bringing huge economic and social benefits.
