| Abstract: | A carbon dioxide density detection instrument used in agriculture is designed by use of the infrared carbon dioxide gas sensor. Blocking structure of hardware and software is designed to improve the universalness and flexibility of the system. By virtue of perfected-function single-chip microcomputer control system and a series of effective compensation measures, it can achieve multi-point and multicenter remote measure and exact control, and its accuracy reached 2%.The system can be used in greenhouse control, preservation of vegetables and other agriculture production and scientific research fields. |
