The Internet of things (IoT) is a networked system consisting of interconnected physical devices that allow data transfer between each other. The physical devices collect data from the environment and transfer the data to the system or other devices to control, monitor, and analyze data. The IoT-based smart lighting system developed in this project is a system that detects light intensity and movement in the surroundings and adjusts the lighting system accordingly. The system's objectives are to reduce electricity consumption and bring more convenience to the users. Moreover, the system was developed according to the project flow, which covers the planning, research, design, and development phases. The components used in the developed system were LED, breadboard, ESP8266 Wi-Fi module, jumper wires, infrared (IR) sensor, and light-dependent resistor (LDR) sensor. The system functions in a dark environment by turning on the LEDs whenever motion is detected near the IR sensors of each LED. Lastly, the developed system was tested and proved to be energy-saving.
