Design of Smart Home Control System Based on Internet of Things

For the limitations of the traditional smart home system that the use range is limited to the near distance and the control mode is single, a design scheme of smart home control system based on Internet of things(IoT) is proposed. The system mainly consists of STC12 Microcontroller node, STM32 master controller and server. The node carries the controlled home devices and communicates with the master controller through NRF24L01 wireless radio frequency(RF) module; The master controller provides an operation interface and communicates with the server through Wi-Fi. The server deploys the website for users to access. The system can control the home locally by the master controller, and control the home, collect and display environmental information remotely by mobile phone or computer. The system has strong reliability, low power consumption and easy expansion.
