Application of carbon dioxide sensor in greenhouse cultivation

With people's deep understanding of gas sensors, these gas sensors will be used in more environments. Of course, it is also necessary for users to ensure its sensitivity and stability when using it.

In recent years, with the continuous publication of smog and PM2.5 in the newspapers, it has occupied the public's vision, and the related gas sensors have gradually attracted the attention of various industries. Despite the poor weather conditions, the carbon dioxide sensor in the gas sensor has become popular. Below, I will briefly introduce the application of carbon dioxide sensors in greenhouse cultivation.

Carbon dioxide sensors can be widely used in agriculture, aquaculture, and industrial fields, such as: greenhouses, animal husbandry, beer, carbonated beverages, energy-saving and environmentally friendly products, and safe production of underground operations. In our daily life environment such as: kindergartens, schools, office buildings, shopping malls, supermarkets, stations, hospitals and other public places, the monitoring of carbon dioxide concentration can improve the quality of air, thereby improving the efficiency of learning and work; prevent the spread of infectious diseases and ensure Public health and safety, let's talk about the application of carbon dioxide sensors in greenhouse cultivation.

Carbon dioxide is one of the raw materials for photosynthesis of green plants, and 95% of the crop's dry weight comes from photosynthesis. Therefore, the use of carbon dioxide sensors to control the concentration has become an important factor affecting crop yields. Plastic greenhouse cultivation keeps crops in a relatively closed place for a long time. The carbon dioxide concentration in the shed changes greatly within a day. It reaches a maximum value of 1,000 to 1200 pp before sunrise, and drops to about 100 ppm 2.5 to 3 hours after sunrise, only the atmospheric concentration. It is about 30%, and it has been maintained until 2 hours in the afternoon before it began to rise, and returned to atmospheric levels around 4 pm. The concentration of carbon dioxide required for vegetables is generally 1000 ~ 1500ppm. Therefore, the shortage of carbon dioxide in plastic greenhouses is quite serious, which has become an important factor affecting the yield of vegetables in plastic greenhouses. Installing a carbon dioxide sensor in a plastic greenhouse can ensure timely alarm when the carbon dioxide concentration is insufficient, thereby using gas fertilizer. Ensure that vegetables, edible fungi, flowers, traditional Chinese medicines, etc. are brought to market early, with high quality and high yield.

Of course, not only the carbon dioxide sensor is widely used in gas sensors, but other gas sensors, such as dust sensors and oxygen sensors, are also widely used. With the deep understanding of gas sensors, these gas sensors will be used in more Environment. Of course, it is also necessary for users to ensure its sensitivity and stability when using it.

Tier 1 Solar Panel

Chinese Tier 1 brand Solar Panel (Longi, Jinko, Trina, Canadian, Ja etc.)

This type of product is mainly Tier 1 solar module product in China, include Longi solar panel. Jinko solar panel, Canadian Solar panel, ja solar panel etc.all of which are among the top 10 world-renowned brands. The original A grade product is mainly mono crystalline and half cut cell solar modules, with a power range of 400watts to a maximum of 700watts.quality warranty is 25 years.

A grade, this type of film is characterized by a neat and uniform appearance, printed electrode grid lines, no broken grid, no surface stains, no leakage, no aluminum package, no hidden cracks, no scratches, no black core, no reverse current, stable electrical performance, and high conversion efficiency
Using solar cell testing equipment to measure and screen, the conversion efficiency, filling factor, and appearance that meet certain standards are first level. Generally, the conversion efficiency, filling factor, and appearance of first level are better than those of level B
The level of solar panels can be divided into first level, second level, third level, and fourth level, and the first level components can be divided into first level+and first level - two levels. The second level is also the same, and the cost difference between different levels of solar panels is also very large.
