Automatic Control Sestem For Environmeng Parameters In Greenhouse

Greenhouse is the important means of modernization of agricultural production. The use of modern technology to achieve the production process and the automatic control of management, can save a lot of human and material costs. It is the powerful guarantee of improving productivity and production efficiency. In the paper, using the greenhouse temperature, humidity, carbon dioxide concentration as the environment parameters realizing control, a kind of automatic measurement and control system for parameters is designed and developed, that is based on microcontroller, and comprehensively uses computer control technology, electronic and automation technology. In the system AT89S52MCU as the control core, the superior sensor as parameter detection means, the stable and reliable actuator as parameter control method, and the efficient and reasonable design of hardware and software is used. The system has the advantages of simple structure, low cost, high efficiency, reliable operation and good portability, and has good application prospect.
