Intelligent Greenhouse System Design Based On Agricultural Internet Of Things

China has always been an agricultural country from ancient times to the present,but there is less land to provide for so many people,and agriculture is always weather-dependent.Therefore,it is always important to increase production and improve food quality and safety when the land is limited.Meaningful things.However,there are many uncontrollable factors in outdoor planting,and it is difficult to solve the above problems.Intelligent greenhouse planters can use sensors to read environmental factors such as light,moisture,fertilizer,and carbon dioxide,and control the corrESPonding controllers to create a steady state suitable for plant growth in agriculture.Environment,improve production efficiency,yield,and improve the quality of plant growth.There is still a certain gap between Intelligent greenhouses in China and developed countries.Therefore,improvement and optimization are made in aspects such as wireless transmission of intelligent greenhouses,simple and easy to understand upper computer,simple control operation,personal data viewing and video monitoring,and cost reduction.This design uses the STM32F103CT86 as the intelligent greenhouse main control core,using high-precision sensors to read the greenhouse environment air temperature,humidity,brightness and other factors,and then use WiFi to capture the collected environmental data in real time to the server,and use the MJPG-streamer connect OpenWRT router.The streamer software’s USB camera capture video surveillance is made into the video surveillance system.After the router passes the Ngrok reverse proxy,the external network can also view the plant growth status in real time in the greenhouse.The mobile phone App can monitor environmental factors(including video)in real time and automatically The environment regulates the growth of a suitable greenhouse plant to provide a suitable greenhouse environment.Finally,the system obtained the results through simulation tests.The App is simple and easy to understand,the operation of the automatic or manual control is simple,the viewing data and video monitoring are convenient,and the actual working conditions and requirements of the intelligent greenhouse are met,and the cost is also low.
