Abstract Abstract

With digital technology has made rapid development and penetration into all areas ,the rising of electronics and information technology, control technology, information society gradually accelerate have prompted people's lives, work, learning to closely communication , people housing requirements are no longer simply a matter of space, but more attention is a highly secure, comfortable and convenient and beautiful living environment,for example advanced communication facilities, complete and efficient information terminals, automated, intelligent home appliances, network resource management,and etc . The growing needs of society makes intelligent home has become a trend today. Smart home system is a hot area of research covered the frontier of intelligent control, electronic technology, communication technology, sensor technology. Its research and applications has great theoretical and practical significance.

This paper presents a control method of smart home system based on an embedded microprocessor STM32 microcontroller to achieve the intelligent control of the smart home system. This paper describes the principles of smart home control systems , the design of the control circuit, the power supply circuit and each module circuit smart home system in detail, focusing on the preparation of the MCU control circuit design and application. Using professional software Altium Designer draw PCB map and schematic, and proofing produced a hardware circuit; Using ESP8266 wireless module for remote wireless communication information of control system, can realize remote wireless monitoring; MQ-7-type carbon monoxide Household gas sensors is used in each room to monitor the concentration of carbon monoxide gas; STM32 microcontroller programming software is Keil μVision4 . And ultimately the design of intelligent home control systems.
