Design of Smart Home Control System Based on STM32
Based on the investigation of existing products,a design scheme of smart home control system is proposed.The design adopts STM32 as the main node and is equipped with Wi-Fi network module to realize the communication between the main controller and Android application.With the help of MQTT protocol,data transmission and message processing are carried out.Through the LVGL graphic UI library installed in the touch screen of LCD serial port,a concise interactive interface is realized,so that users can control household equipment more conveniently.Various sensor technologies are used to collect indoor environmental data in real time and process and analyze them.The design can set different intelligent control strategies for different application scenarios in different time periods,realize automatic home control,and ensure the data and privacy of users by using data encryption and user authentication.The system gives full play to the advantages of modular design and has a good price-performance ratio.
