Design and Experiment of Control System for Intelligent Agriculture based on Arduino

With the development of modern agricultural production technology, intelligent agricultural production has become the development trend of modern agricultural production. This paper designs a smart agricultural greenhouse control system that can collect, display and control the temperature, humidity and light environment in the greenhouse in real time. The system is based on the Arduino mainboard, using temperature and humidity sensor DHT11, light sensor GY-30, relay and LCD display to realize the real-time collection, display and control of temperature, humidity, and light intensity in the greenhouse. The detection and optimization debugging of the physical system shows that the system can respond in time after the environmental conditions exceed the suitable range of the crops, and control the temperature, humidity and light environment in the greenhouse through the relay, and display them in real time.
