Design of Intelligent Greenhouse Environment Monitoring and Control System Based on Qt

This article combines the Internet of Things technology and modern agricultural production, and designs a smart greenhouse ecological environment monitoring and control system based on Qt (Qt is a cross-platform C++ graphical user interface application development framework developed by Qt Company) as the development environment. The system selects Arduino Uno control board as the lower level controller, and can monitor important environmental parameters such as temperature and humidity, soil PH value, NPK (nitrogen, phosphorus and potassium) content of the smart greenhouse in real time through various sensors. And the system can automatically adjust greenhouse environmental parameters by controlling the irrigation system, roller shutters, fans, shading curtains and other facilities in the greenhouse. The test results show that the intelligent system designed in this article can accurately measure the environmental data and complete the adaptive control of environmental parameters of the greenhouse, meeting the needs of modern agriculture.
