Abstract:In order to be fast, accurate monitoring some parameters of household environment, constructed a kind of smart home monitoring system based on the wireless sensor network. The system consists of multi-sensors to collect temperature and humidity, smoke, steal affection environmental data, the data through the NI WSN nodes by wireless way sent to the PC, PC using LabVIEW software programming the processing of data judgment and control, has obtained the good human-computer interaction interface, including detailed introduction of system software design flow. The smart home monitoring system has the characteristics of the wireless sensor network (WSN), low power consumption, good real-time, easy to expand, remote monitoring, etc. It will enjoy a promising market and can be applied widely in the field of smart home.
