摘要
本系统是利用单片机技术设计的多功能自动调光器,能够通过红外感应模块检测到环境中是否有人存在,进而控制白炽灯的亮灭,实现了白炽灯自动开关的功能,大大方便了人们的日常生活。此外,系统还利用光敏电阻对环境光照强度的敏感特性,采集相应的电压信号,通过STC89C52单片机处理后,利用定时器产生相应的脉冲信号来控制双向可控硅,从而达到自动调光的效果,并且用液晶1602显示白炽灯的亮度级别。
This system is designed for multi-purpose use of SCM technology automatic dimmer environments exist if someone is able to detect the infrared sensor module, then control of incandescent light off, to achieve the incan- descent automatic switch function, greatly facilitate the people everyday life. In addition, the system also uses photosensitive resistance to the sensitive nature of the ambient light intensity corresponding voltage signal acquisi- tion, through post-STC89C52 microcontroller processing, use a timer to generate the corresponding pulse signal to control the triac, so as to achieve the effect of auto-dimming, and 1602 with LCD display brightness level incan- descent.
