Abstract: Aiming at the problems of disorder and difficult customization of personalized functions in micro agriculture planting, a set of cloud service system for micro agriculture is designed. The system includes four parts: detection node, communication gateway, cloud server and terminal interaction system. The detection node is implemented at the planting site, including soil temperature and humidity sensor, air temperature and humidity sensor, illumination sensor, etc., which mainly collects various parameters; The communication gateway receives the node data and transmits the data to the cloud server; The ECS stores and analyzes the data, and uploads the processing results to the upper computer; The terminal interactive system can monitor various parameters online and quickly control the equipment, so that the crops in the planting area can always be in a suitable growth environment. Using the collected data, the cloud server can realize the corresponding temperature and humidity control through the fuzzy controller. The results of simulation and actual operation experiments show that the system runs stably and can meet the requirements of personalized customization, standardized implementation and information management of micro agriculture.
