With the rapid development of electronic, computer and communication technology and the improvement of people's living standard, people have higher expectations for the home furnishing function. To improve the difficult situation of wiring and maintenance in the most fieldbus system, this paper provides a smart home system solution based on ZigBee Wireless Sensor network. This System includes ZigBee Wireless Sensor network, smart home system gateway and mobile phone end device. Users can master the working state of all the sensors in the nodes intuitively, and they can centralize control the Electrical appliances. And the remote control mode can be realized through a mobile terminal, too. After the test, this system works well and reaches the desired design goal.
