摘　　要：采用红外二氧化碳气体传感器设计了农业设施专用的二氧化碳浓度测控仪。其软硬件均为模块化结构,能够增强系统的通用性和使用灵活性;借助于功能完善的单片机信号处理控制系统,并配合一系列有效的补偿措施,完成二氧化碳浓度多点多通道远距离测量和准确控制,其相对误差小于2%。该系统可广泛地应用于温室大棚、蔬菜储藏以及其它农业生产和科研领域。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.
