智能照明系统设计：基于单片机的光照度自动调节方案详解

As an important part of household electricity consumption, smart lighting has broad development prospects. With the increasing awareness of energy conservation, designing lighting devices that can adjust their brightness according to changes in light intensity is becoming necessary. In response to this issue, this design uses a light sensor module to collect environmental light intensity, and then uses the STC89C51 microcontroller to control the brightness of the light, completing real-time detection and display of light intensity. Additionally, the system can adjust the brightness of the light accordingly. The complete design includes hardware circuit design, software program coding, and simulation using Proteus. The simulation results indicate that the design successfully achieves real-time detection and display of light intensity and can appropriately adjust the brightness of the light. Key words: smart lighting; light intensity detection; STC89C51; automatic light control.
