Based on ARM920T kernel S3C2440, embedded Web services, QT technology and wireless networking technology, a smart home monitoring system was designed. The system was composed of a host of smart home, ZigBee/Wi-Fi wireless sensor control network and smart home client software. The hardware and software design of the host of smart home was completed:the embedded Linux operating system was transplanted in the ARM platform; the embedded Web services were established by using gSOAP tool; USB to serial driver and Wi-Fi wireless LAN (Local Area Network) driver were configured; ZigBee wireless sensor control network was formed, the program design of the coordinator node and terminal node was completed, the data communication protocol was made, and the client program was designed by using QT technology. Finally, the tests of establishment of ZigBee network, terminal nodes joining the network and sensor node data transmission were done. The test results show that the sensor nodes in the network can transmit the detection information to the coordinator, and the smart home client software can complete the remote monitoring and control of home environment through the host of smart home.
