摘要
介绍了高性能环境光传感器TSL2581的基本特性和软硬件控制设计方法,搭建了隧道灯光按需照明调光系统,以STM32微处理器为核心,输出直流电压控制LED功率,利用TSL2581检测隧道照明亮度。测试表明,系统能实现公路隧道照明亮度检测与节能优化功能。
The basic characteristics of the high performance environmental optical sensor TSL2581 and the design method of the hardware and software control are introduced. The dimming system of the tunnel on-demand lighting is established. With the STM32 microprocessor as the core,the output DC voltage controls the LED power,and the brightness of the tunnel lighting is detected by TSL2581. The test shows that the system can realize the highway tunnel lighting detection and has the energy optimization function.
