The design of smart home based on Internet of things

Abstract With the continuous improvement of the current era of economic level as well as the Internet technology comprehensive promotion and application, people for life quality requirements are also increasing year by year, generally speaking, safe, convenient, comfortable and relaxed is common people's life goals. In recent years, people’s requirements for the family living conditions have changed a lot, smart home will become more and more people love, more and more dependent on the advanced residential.

In this paper, the development of smart home and application prospects were introduced and studied. Among them, the focus of the Internet of things smart home design of wireless communication technology. Then, based on the LEACH algorithm, the application design of the related technology of the Internet of things is analyzed and studied. Wireless intelligent monitoring system uses the microcontroller NRF24L01 and RF communication chip STC12C5A60S2. Through for the electronic system, induction system, micro control system, serial interface circuit, communication subsystem, alarm subsystem, display subsystem and the key subsystem hardware design, and system main flow, node software function, gateway software function, low power consumption LEACH algorithm, the completion of the smart home development and utilization.
