Design and implementation of smart home control system based on STM32

Abstract

In order to solve the shortcomings of the traditional smart home server, the development and implementation of a novel embedded smart home control system based on STM32F407VGT6 microprocessor and μC/OS-II embedded real-time operating system is proposed in this paper. The hardware implementation and software design of embedded smart home control system based on STM32 are described in detail. The proposed hardware architecture is composed of remote user application terminals, the terminal control unit and various terminals distributed in different rooms. The communication between the terminal control unit and the field terminals is implemented using ZigBee technology. Moreover, the temperature and humidity digital composite sensors DHT11 are used to collect real-time data of temperature and humidity in different rooms. Then, the dual-band GSM/GPRS module SIM800A is selected for information transmission of sensor data and remote commands. The final experimental results show that the remote terminal can realize the control of the field intelligent appliances. Remote users can also easily browse the household temperature and humidity data using the mobile APP or the web page.
