| Summary: | Agricultural greenhouse cultivation technology is of great significance to modern agricultural production. In order to solve the problem of on-line collection and monitoring of environmental information in agricultural greenhouses, a meteorological environmental data monitoring system for agricultural greenhouses based on Internet of Things was designed. The design used CC2530 RF module as the core chip of the terminal acquisition device. Agricultural greenhouse meteorological observation station was set up by arranging sensors such as light, soil moisture, air temperature and humidity. Short-range wireless communication was developed and corresponding specifications was established based on Z-Stack protocol stack. Collected data was based on MQTT to do push and pull of information. The system′s practicability, low cost and short development cycle was ensured by the software and hardware development of the system.After the actual use of agricultural greenhouses, advanced technology, flexible design, low cost, simple layout and high cost performance were owned by the system designed in this paper, which can effectively complete the on-line monitoring of meteorological data in agricultural greenhouses as well as provide meteorological monitoring basis for other agricultural systems.
