Design and Realization of Smart Home System Based on Wireless Sensor Networks

Abstract

The paper takes STM32 microcontroller as the core. The UIP protocol stack is transplanted to STM32 to construct embedded web server and wireless sensor networks is used to construct the internal network of smart home. In combination with GSM communication technology, a smart home control system with the advantages of reliability, simplicity and flexibility is designed. In addition, this article also introduced a low power wireless receiving and transmitting chip CC 1100 in detail, completed software and hardware design of wireless receiving and transmitting module. Aspect of hardware design, completed the peripheral circuit design of CC 1100 and design of interface circuit .Aspect of software design, completed setting of register, communication of SPI with single chip and receiving and transmitting of data, has given the flow chart and the procedure.
