Usage of lamp in workroom represent primary factor in modern human life in this time. With exploiting natural light (sunlight) what enter in house workroom remain, we earn to control illumination in the room with condition of lamp in five situation of illumination that is gloomy, rather gloomy, rather bold, bold, bold progressively. Big of illumination in room defended equal to 250 Lux.. This system consist of five especial block, that is network sensor use LDR, Network of ADC 0804, Mikrokontroler AT89S52 , network of RS 232, and Network of driver network (Optotriac and Triac). Network sensor uses to detect light so that can yield output voltage (Vout) which later will become input to network of ADC 0804. From ADC, the voltage converted to become digital data so that can be processed by mikrokontroler. The function of Mikrokontroler is to process the digital data from ADC which is later used to arrange angle of the triac at the driver network and the connect the data trough pc. Driver network uses to arrange the value of illumination that is determined by group of potensiometers, while network of RS 232 used for serial communications between the system and the pc. The LDR sensor can work with linear respon to change of the illumination as the voltage from the network sensor is linear to the illumination the greater illumination by network sensor hence the smaller output voltage yielded by sensor network. System can work as its expected that is, the illumination in the work room has 244 lux of average with 22Lux of standard deviation of illumination.
