Abstract:

With the development of socio-economic, people have began to pursue more personalized and automated life. The demand for thequality of home environment is increasing highly, people requiring for the intelligent living environment and strong security. Nowadays, based on embedded systems and network technology, smart-house technology is booming which puts user’s experience as the core-oriented, has broad application prospects. A kind of smart-house monitor system platform based on wireless sensor networks has been designed in this paper. The temperature value, smoke density value and CO density value in the environment have been collected through temperature sensor, smoke sensor and carbon monoxide sensor, all these infromation are transmited to the controller through the Zigbee wireless network using CC2530. With a video monitoring module, the instant video message is transferred at the same time. The embedded ARM11 chip is adopted in this system as the controller. A kind of Android Web server has been built through the transplant of Android system, the mainstream operating system, and the introduced of the i-Jetty server. The data of system has been stored with SQLite database technology. The server can be logged in through the Web browser of the mobile phones or personal computers to achieve real-time monitoring of smart-home system.
