On Linux system ,we use python and control light ,curtain, GPIO,switch electric kettle and listen to the music on Internet by mobile phone. Temperature measurement, monitoring and alarm system is as well. Key words-Raspberry Pi Smart Home Linux 0 FORWARD THE goal of home automation is to make our home life more fun and efficiency, and the concept of "intelligent" was introduced into home. In this article, we take full advantage of the open source nature of Raspberry Pi, and choose Linux as our underlying system, using open source software to complete intelligent home-control functions that we want to achieve. We use Python language, taking advantage of its convenient language features. In our work, Raspberry Pi is a perfect relay point, because of the use of wireless network technology, we achieve a mobile remote control lights, remote control curtains, remote control switches giving the kettles boil water supply, watercress FM broadcast implementation of a smart home entertainment system and Pyroelectric sensor to achieve the alarm function, and the application of mobile video surveillance reflect smart home security system.

Although its appearance "petite" inner "core" is very powerful, video, audio and other functions all Jie, is a "small but perfectly formed." In our development process, we chose the Raspberry Pi of B-type version, it is a miniature ARM-based PC motherboard, on which includes a ARM1176JZF-s 700Mhz processor (can be overclocked to 1Ghz), and a Video Core IV GPU, there are 512M RAM, no built-in board above the long-term storage devices, memory, hard drive to SD card, the card around the motherboard has two USB ports and one Ethernet port can be connected to the power supply, keyboard, mouse, and network cables, and has TV-out connector on the video analog signals and HDMI high definition video output interface, the above parts are all integrated on a motherboard only slightly larger than a credit card, with all the basic functions of a PC simply turn the TV on and keyboard, you can perform such as electronic spreadsheets, word processing, play games, play high-definition video and many other features. Raspberry Pi computer board only, no memory, power supply, keyboard, chassis or connection. Overall, the Raspberry Pi board rich external interface, the processor, the storage device is not strong enough, but its low price, provides us with an ideal platform for embedded development.
