Development of Automation System for Room Lighting Based on Fuzzy logic Controller

Aryanto Hartoyo and Seno Darmawan Panjaitan

Abstract—This paper describes the development of fuzzy logic controller for room lighting system using AT89S51 microcontroller. The fuzzy logic system has two membership functions for the light sources as inputs and one membership function for the output. The first light source is from the outside and the second light source is available in the room. The other input to the control system is from the occupation sensor. The output membership function of the control system is used to determine the number of compact fluorescent lamp (CFL) that must be turned on. The control system will switch the CFL on or off according to the condition of the illuminance in the room. The room illuminance is based on Indonesian National Standard which is about 250 Lux. In case the room is empty, the controller will turn all lamps off. The result of experiment showed 23.9 % in power saving and 4.1 % in difference of control system output to the reference.
