With the continuous advancement of technology and the improvement of living standards, people’s demands for quality of life and convenience have been steadily increasing. Smart home technology, as a significant application area of modern technology, has gradually garnered attention and pursuit. Within the realm of smart home technology, lighting control stands as an important facet, playing a crucial role in enhancing residential comfort, conserving energy, and elevating user experience.The aim of this project is to design a smart light control system based on the STC89C52 microcontroller. The system has the following main features: simulating five rooms with LED lights (living room, three bedrooms, and bathroom), using five buttons to control these five lights. Additionally, a human body pyroelectric sensor module is installed in the bathroom, which automatically turns on the lights when a person is detected and the light is low. Users can adjust the brightness of the living room light using specific buttons and also change the color of the three bedroom lights using three other buttons. Furthermore, the system supports Bluetooth connectivity to control the on/off state of the five lights, as well as adjusting the color of the bedroom lights and the brightness of the living room light from a mobile phone.By utilizing microcontroller control, LED light simulation, human body pyroelectric sensing, button input, and Bluetooth communication technologies, this design achieves intelligent control of multi-room lighting. Through remote control via mobile phones and automatic sensing, users can easily operate and adjust room lighting, enhancing the comfort and convenience of the home environment. This design not only meets the needs of daily life but also provides a practical solution for the development of the smart home field.
