This project aims to design and implement an intelligent home lighting control system based on the STC89C52 microcontroller, achieving smart control of household lighting. The system includes simulated LED lighting control for three rooms, brightness and color adjustment, human body sensing automatic switch, timing control, and Bluetooth remote control via smartphones. Through this system, users can conveniently control household lighting, enhancing living comfort and energy efficiency.Key features:Simulated LED lighting control for three rooms: Utilizing the STC89C52 microcontroller, the system simulates the lighting control for the living room, bedroom, and restroom. Users can operate the lighting using buttons.Brightness and color adjustment: The system provides three buttons for controlling light brightness and another three buttons for adjusting light colors, enabling personalized lighting settings.Human body sensing automatic switch: A human body pyroelectric sensing module is installed in the restroom. When it detects a person in low light conditions, the system automatically activates the lights, providing convenient illumination.Timing control and countdown display: Users can set the activation time for the bedroom light. The system initiates a countdown and displays the remaining time on the screen. Once the set time is reached, the light automatically turns off, allowing users to control nighttime lighting.Bluetooth smartphone remote control: By connecting to smartphones via Bluetooth, users can remotely control the on/off state of the lights in three rooms and adjust the brightness of the living room light, achieving convenient remote control functionality.Through this intelligent lighting control system, users can freely adjust household lighting according to their needs, enhancing their quality of life while achieving energy savings and intelligent management.
Keywords: Intelligent lighting control system, brightness adjustment, color adjustment, human body sensing, Bluetooth remote control.
