Smart lighting system is known as lighting control that provided an efficient way to
reduce energy consumption. This research proposed an Arduino based smart home
lighting control device to achieve a low power consumption, cost effective and flexible
home automation system. The system deals with the construction and interfacing of
essential components such as Arduino, LDR sensor, PIR sensor, DS3231 real time
clock (RTC), relay and LED light bulb. Arduino works as main controller to control
every action of the lights through programming and connection among the sensors
and other electrical auxiliary components. The input LDR and PIR sensors are used to
detect the light intensity and motion, respectively. On the other hand, a DS3231 RTC
is used to maintain accurate timekeeping and trigger the relay in a specific time. A
complete system is demonstrated through a smart home lighting system prototype
model. The testing and validation of prototype model shows that the proposed system
can work properly and can contribute to improvement of building’s energy
consumption.
