Research On Monitoring System Of Intelligent Household Environment Based On ZigBee

Modern intelligent household has already developed from initial cable transmission to wireless communication, based on the four kinds of technology such as ZigBee, Wifi, Z-Wave and Bluetooth, which can be set up through automatic networking according to the need of the household devices with the advantage of high expansibility, arbitrary embedded property and easy update.ZigBee technology has the advantages of high security, good network stability, large network capacity(theoretical nodes 65300), which has the ability of two-way communication. Moreover, ZigBee technology can use the battery power and adopt ultra low power design, which the theory life of a battery can reach 10 years with the properties of energy conservation and environmental protection, so ZigBee technology gradually becomes the main communication technology in intelligent household.In this paper, ZigBee technology is acted as a design tool and household environment is acted as a monitoring object, and gas leakage, air quality, oxygen concentration and temperature and humidity are set as the monitoring information. According to the set goals, the suitable gas sensor and temperature and humidity sensor are selected as the core module, and each module in intelligent household system is well designed and test a serious of functions. The wireless technology is used in household system of the whole backbone network, which can make household system completely get rid of the dependence on the cable, and take full advantage of wireless technology, while can promote intelligent household industry as a whole to move forward.
