As a part of the Internet of things, smart home industry is growing rapidly with the continuous improvement of peoples living standards. Smart home gateway between main responsibility is to ensure that the variety of terminal equipment connect with each other, at the same time also need to realize the centralized control of multiple devices, Internet access and multiple functions such as remote control. Smart home gateway as the main hub of smart home, in the practice of the method of using wireless network, to create a smart home and select the embedded system for smart home network services. This project designs an intelligent home monitoring system based on the ZigBee technology and OpenWrt technology, The system will be combined with a short distance control, remote monitoring system of household wireless control and data acquisition, avoid the difficulty of integrated wiring, has good scalability. This paper introduce the wireless sensor network simply,and it mainly studies the ZigBee technology, protocol specification, the connection between the networking and communications. Using MT7620A OpenWrt system and ZigBee wireless communication technology,we achieve the smart ho
