Design of Hierarchical Monitoring System for Crop Growth Environment Based on Arduino Yún Development Platform

Based on the scientific and technological plan of Shandong Province and the vocational education reform project of Shandong Province, this paper carefully designed a hierarchical monitoring system for crop growth environment based on Arduino Yún development platform after analyzing the current development of agricultural equipment in China. The system uses DHT11 temperature and humidity sensor, GY-30 light intensity sensor and MG811 carbon dioxide concentration sensor to collect environmental information, which is designed from three aspects: sensing layer, transmission layer and application layer to realize intelligent control of the environment inside the agricultural greenhouse. The cost of agricultural production and the labor intensity of employees will increase the quantity and quality of agricultural products and achieve the goal of automation and intelligence of agricultural production.
