How to make the vast majority of consumers can enjoy the experience of low-cost smart home electronics sector has been an important research topic. For this reason, in order to design a set of STM32 ARM Cortex-M3 core as a master of smart home systems. The system has an outstanding low power performance as well as numerous peripherals powered by the open source μCOS embedded real-time operating system to achieve intelligent home control. Experimental results show that the system is stable, power control in 5W, implements indoor voice recognition, to identify the correct rate of 88%, internal/external network remote control of home appliances, while both remote video monitoring and security facilities, has broad application prospects.
