This article put forward a method to realize the transmission between wireless sensor network and the Internet. The IOT (Internet of Things) gateway is used as part of the greenhouse monitoring system. The design compatible multiple access method such as LAN, Wifi, GPRS, EDGE, 3G and so on, also the data can stored locally. The IOT gateway uses STM32 as the MCU, mC/OS-III as the embedded operating system. The application demonstrates the gateway is reliable, compatible, and extendible. Because of this gateway the greenhouse monitoring system realized the real-time detection and control of the greenhouse, and improved the ability of the automation and the intelligent of the greenhouse monitoring.
