This thesis has designed a temperature control system which takes Micro controller Unit AT89S51 as the core. Temperature signal received from sensor DS18B20 is analysed by AT89S51. It adjusts temperature using relay heating wire and fan. 1602LCD display the current temperature value and buzzer could give an alarm. The system can detect and regulate temperature in real time. It contributes to production efficiency.

There are many changing factors in a greenhouse, and the traditional control method has been unable to obtain a good control effect. In this study, focusing on the fuzzy neural network (FNN), the principles of two control methods and the advantages of their combination were analyzed, an intelligent remote control system for a greenhouse based on the FNN that controls the temperature and humidity was designed, and a simulation experiment was performed in the Simulink environment. The results demonstrated that compared with the traditional proportion, integration, differentiation (PID) control system and the genetic algorithm + fuzzy PID control system, the FNN-based system designed in this study achieved better performance in temperature and humidity control. The temperature error of the FNN-based system was smaller than 1◦C, the humidity error was approximately 2%, and the change in the error values was stable. The experimental results verify the reliability of the FNN and provide some theoretical basis for the intelligent control of greenhouses.
