Design of an Embedded Automatic Control System for Temperature and Humidity and Illumination Intensity of Agricultural Greenhouses

After analyzing the current development needs of agricultural equipment in China, an automatic control system based on embedded temperature and humidity and illumination intensity of agricultural greenhouse is designed. The system is based on STM32, with temperature and humidity acquisition module, lighting acquisition module, display module and corresponding executing mechanism. It has the obvious advantages of accurate control, simple structure, convenient operation and high cost performance. It is suitable for small and medium-sized farmers in most areas of China.
