Abstract: Intelligent home furnishing as family information realization way, has become an important part in the development of social informatization, network because of its great application prospect, is the intelligent home furnishing industry is in the process of developing a practical breakthrough, intelligent home furnishing industry development has great sense. In this paper, based on the easy implementation convenient operation, close to the use of the design concept, design of intelligent home furnishing system is based on AT89C51control device, the two part through a wireless communication module for data exchange. Host is the core part of the system, through the keyboard input module of the system of temperature and humidity for initialization, and the use of LCD display module on the indoor condition real-time display, this part also has a temperature and humidity control and gas valve switch control function, the abnormal condition, system through sound and light alarm module alarm, to achieve intelligent control of home furnishing.
