The design of smart home system based on wireless sensor network

With the rapid development of WSN technology and the improvement of people´s living standard, the intelligent home environment and security requirements are also increasing. This paper proposes a smart home system design based on Wi-Fi wireless sensor network and describes respectively from the design of Wi-Fi network, the node hardware design, the software design functional processes. The design uses ARM9 chip real-time operating system to achieve a Wi-Fi wireless network management, home environment data acquisition, data transmission, analysis and processing, and then sends commands to control relevant equipment. Taking smart home system as its platform, the design sets systems, structures, monitoring, management in one, and has broad application prospects and promotional value.
