With the development of automatic control technology and the popularization of agricultural science and technology, people are more and more aware of the intelligence convenience. In this study, a set of intelligent greenhouse temperature control system is established based on single chip microcomputer STM32F103. PID algorithm is used to realize stepless adjustment of greenhouse temperature, and complete the temperature automatic monitoring and control. It solves the greenhouse problems of low automation degree, large amount of manual work and low control accuracy of crop growth environment. The system simulation and practice show that it can improve the temperature and humidity control accuracy of greenhouse by 10.8%, and reduce the amount of manual work, and provide a good natural environment for plant growth and dev... 更多
