Carbon Dioxide Sensor

Carbon dioxide is one of the raw material for photosynthesis in green plants, crop dry weight of 95% comes from photosynthesis. Therefore, using the concentration of carbon dioxide sensor control has become an important factor in crop production. Crop cultivation in plastic greenhouse in a relatively confined space for a long time, greenhouse carbon dioxide concentration varies within a day, maximum 1000~1200pp before sunrise, Sunrise 2.5-3 hours 100ppm, only about 30% of atmospheric concentrations, and lasted until 2 hours before beginning to pick up in the afternoon, around 4 o'clock in the afternoon returned to atmospheric levels. Vegetable carbon dioxide concentrations of General 1000~1500ppm. Therefore, the plastic greenhouse carbon dioxide deficit is very serious, becomes an important factor influencing production of vegetables in plastic greenhouse. Installed in the plastic greenhouse carbon dioxide sensors can be guaranteed in the case of insufficient carbon dioxide concentration alarm, and the use of fertilizer. Ensure vegetables, edible fungus, flowers, traditional Chinese medicine, high quality and high-yield early.
