英文摘要：

To improve the automation and informatization of greenhouse production process, a greenhouse environment param ters acquisition node based on ZigBee was designed. Because of the complicated communication protocol stack, it is difficult to develop the traditional ZigBee node directly based on ec2530. To decrease the difficulty of development and shorten the development cycle, the system was developed on Arduino （open source hardware） and wireless serial port based on ZigBee. The system uses SHTIO, BH175FVI and MH-Z18 NDIR to detect temperature and humidity, light intensity, dioxide gas concentration respectively and it takes Arduino Mega2560 as the main controlling kit for real-time acquisition and processing environmental parameters. ZigBee module TBO106 was used to construct ZigBee communications networks and Star-ZigBee-network was used among the collection nodes. The main program flow chart was introduced, and the method of modular design was used in the software design in order to extend functions in the future. Simulation testing experiments show that the system has good stability and high communication efficiency to meet the greenhouse environmental monitoring requirements for network transmission and wireless communication networks, and the high value of promotion and application.
