Abstract
In the process of agricultural production and development, greenhouses occupy an important position, and the combination of Internet of Things technology and agricultural production technology has greatly improved the production efficiency of agriculture.This design is aimed at the environmental monitoring management system of the closed space of the greenhouse. Based on STM32 single chip microcomputer, it integrates multiple sensors to form a wireless sensor terminal node and a sensor network to realize the real-time monitoring of the greenhouses environment. At the same time, the system can also upload the monitored environmental data, including environmental temperature and humidity, soil moisture, light intensity and CO2 concentration data, WiFi module will upload the monitored real-time data to the server, and carry out the corresponding storage and processing operations, the system according to the real-time parameters, the environmental parameters in the greenhouse for corresponding scheduling and processing. The environmental parameters in the greenhouse are in the most suitable range for plant growth. The design can also set the relevant threshold and switch the mode by pressing the button, and display the data in real time through the display screen and the mobile phone.The test results show that the system has stable operation, accurate monitoring, low power consumption and convenient wiring. It provides theoretical basis and technical support for the adjustment of greenhouse environmental parameters.
