模拟路灯控制系统，分白天模式和夜晚模式，模式的切换由DS1302时钟芯片时间来判断，白天模式中通过光敏电阻检测当前光照强度，低于设定的值则灯亮，夜晚模式只有在车辆或者行人通过灯才会亮，检测行人通过是通过红外对管实现。-Street light control system simulation, the points during the day mode and night mode, the mode switch is judged by the DS1302 clock chip time, day mode, the current light intensity detected by photoresistor below the set value, light, night mode only in the vehicle or pedestrian through the lamp will light, the detection of pedestrians through the infrared, on the tube.
