With the continuous progress of smart home technology, the lighting system in the home environment is gradually transformed to intelligence. As an important part of the smart home, the intelligent bathroom lighting control system can automatically adjust the lighting brightness according to the actual needs of users and environmental changes, and improve energy efficiency and user experience. This design adopts STC89C52 single chip computer as the control core, through the integration of sensors, display module and wireless communication technology, to achieve the intelligent control of bathroom lighting, to meet the needs of modern families for intelligent, energy saving.
The system utilizes the D203S pyroelectric sensor to automatically control the bathroom lighting, turning on the lights when someone is present and turning them off when no one is there, saving energy. Users can manually adjust the brightness to meet various needs. The LCD1602 module displays the light intensity and occupancy status, providing real-time feedback. The system is equipped with a built-in Bluetooth module ECB02, which supports remote adjustment of light brightness via a smartphone, achieving intelligent remote control.
The intelligent bathroom lighting system designed with the STC89C52 microcontroller achieves intelligent management of lighting, thereby enhancing the user’s experience. Its remote control function provides users with a convenient way of operation, allowing them to adjust the lighting status anytime and anywhere as needed [3]. The addition of the LCD1602 display module makes the system status clear at a glance, enhancing the user’s interactive experience. The system offers an efficient, energy-saving, and intelligent solution for bathroom lighting, possessing high practical value and market potential.
