Abstract :
This article put forward a technique to realize the communication between wireless sensor network and the Internet. The IOT (Internet of Things) gateway is used as part of the greenhouse checking system. The design well-matched multiple access method such as LAN, Wifi, GPRS, EDGE, 3G and so on, also the data can be deposited locally. The IOT gateway uses STM32 as the MCU, ?C/OS-III as the embedded operating system. The application demonstrates the gateway is trustworthy, compatible, and extendible. Because of this gateway the greenhouse monitoring system realized the realtime detection and control of the greenhouse, and enhance the ability of the automation and the smartness of the greenhouse monitoring
