The Design of Smart Wireless Carbon Dioxide Measuring Instrument Used in Greenhouse
Different crops, seasons, greenhouses structures and planting area need different concentration of carbon dioxide which fertilized in greenhouse. Measuring the concentration of carbon dioxide accurately in greenhouse is very important to fertilize carbon economically and reasonably Concentration of carbon dioxide measuring equipments were often used in chemical industry and environment fields, these equipments are not suitable for greenhouses environment and had many disadvantages such as high price, high power consumption and low antiinterference ability. Based on the research of carbon dioxide measuring equipment, this design took part of Non Dispersive Infrared (NDIR) carbon dioxide sensor produced by GSS, embedded Zigbee module provided by Jennic, smart calibration program and solar panel charge system. The results showed that the accuracy was±30ppm, average power consumption was 2mW, high consistency, response fast. This design can change the present of carbon dioxide measuring instrument hard to popu larize, and make carbon dioxide fertilization accurately.
