ENVIRONMENTAL MONITORING AND CONTROL SYSTEM OF GREENHOUSE BASED ON INTERNET OF THINGS TECHNOLOGY

Greenhouse is an important application scene of modern agriculture. In this paper, a set of greenhouse environmental monitoring, facility remote control and production management system is designed and implemented based on Internet of Things technology for the development needs of modern agriculture in greenhouse. The system selects STM32F407 control board as the main controller to realize real-time monitoring of greenhouse environmental parameters including temperature and humidity, soil nutrients, soil pH and other greenhouse environmental information, and can adjust greenhouse environmental parameters by controlling the irrigation system, roller shutters, fans, shading curtains and other facilities in the greenhouse. The main controller uploads the collected environmental data and the status data of the execution equipment to OneNet cloud platform in time. Users can obtain the environmental data and control the facilities in the greenhouse anytime and anywhere through the terminal monitoring software. he greenhouse environment monitoring and control system designed in this paper improves the safety and automation of greenhouse. The system is easy to operate, can help farmers remotely know the situation of greenhouse and carry out unified management of greenhouse which will greatly improve efficiency.
