With the improvement of living standards and the development of the Internet of Things, the demand for intelligent home is becoming more and more urgent. This paper describes the design and implementation of smart home based on raspberry pie. Through raspberry pie as the main module, we build a smart home system to meet the needs of the public. This system takes raspberry pie as the main development platform and develops a smart home solution based on Ubuntu operating system, it contains a speech synthesis, speech recognition, image recognition, data acquisition, AI dialogue, video monitoring, voice control, voice logging, etc. Interact with robots and sensors through voice, WEB, WeChat, and APP. It can interact with robots and sensors through voice and mobile WeChat, and can log in the Web interface to view the underlying data and control the sensors accordingly. The system sensor part adopts ZigBee communication protocol, and MQTT communication protocol is adopted for communication with the server. The two communication protocols are of low cost, low power consumption, and saving network resources.
