We use of the simple manually controlled in most greenhouse in China and it has low productivity,the unit production costs are high.
This design is the intelligent control system for greenhouse and mainly by the control and display two modules. Temperature controlled by the MCU STC89C52.It will automatically colling when the temperature exceeds the standard and we use the small fan to drop the temperature. Temperature acquisition using DS18B20. Different locations in the greenhouse as long as one DS18B20 can collect the temperature and to facilitate the observation and control.I use the LCD1602 to display the data.
This thesis talked about the hardware and software design of intelligent control system for greenhouse,the function of the MCU STC89C52, the temperature sensor DS18B20 and each modules.
Keywords: Intelligent control system for greenhouse, MCU STC89C52, DS18B20.
