Design And Implementation Of Smart Home System Based On Android And Wi-Fi

With the concept of the Internet of things and the development of science and technology, Smart home has a new direction of development, and gradually close to the people’s lives. People’s higher pursuit of quality of life, so that the development of smart home has been a huge leap. Since the United States designed the first Intelligent Building, smart home has been a concern. But it’s complex projects and high prices are prohibitive. The development of wireless communication technology and the popularity of smart phones have brought more powerful vitality to the smart home. Intelligent home has an unlimited broad prospects, therefore, the study of smart home system is in line with the development and needs of society.The smart home system is based on Wi-Fi technology and Android platform, which can be used for remote control of home appliances, as well as temperature and humidity, combustible gas monitoring. Main work includes:First, the system uses Wi-Fi wireless communication technology, replacing the traditional smart home needs of the complex wiring, greatly saving the cost. The system adopts ESP8266 module and Arduino module to realize the control of the system and data exchange, plus the corresponding sensor and the peripheral circuit, the design of the data acquisition terminal node, They formed the indoor environment monitoring system. The Android operating system for smart phones will control the data acquisition terminal node by 2G/3G/4G/Wi-Fi these means of communication, so as to implement the electrical equipment monitoring and control and query, always understand the status of home.Then design the application software of smart terminals,after analyzing the demand of terminal software, Android platform development environment to build, and then design a interface of each functional module, including the initial main interface, scene mode configuration interface, electrical equipment control interface, timing task interface, room configuration interface and security interface and realize the corresponding function, such as household electrical appliance switch function, add and set the scene mode, the timing of the task of setting, grouping control household appliances to the room as a unit, as well as the smoke and gas can exceed the alarm function.At last, a series of tests are carried out on each module, tests show that the system is very stable and reliable, the function can be achieved, the measurement data error is negligible, and the system has achieved the initial design of the proposed requirements and indicators. The whole system is of great practical value.
