Abstract

Lighting is a fundamental need in daily life; however, conventional lighting systems that are still widely used today tend to be inefficient due to manual operation. This often leads to energy waste, especially when lights are left on during the day or in unoccupied rooms. This final project discusses the design and implementation of an automatic lighting system based on a light sensor (LDR) and motion sensor (PIR), aimed at improving energy efficiency in building environments. The system is designed to activate the lights only when two conditions are met simultaneously: the presence of a person in the room and low ambient light intensity, using an AND logic as the decision-making basis. Test results show that the system responds accurately, consistently, and reliably to environmental changes, and is capable of significantly reducing electricity consumption. By adopting this automation technology, the system not only supports energy savings and reduces operational costs but also contributes to environmental preservation through the reduction of carbon footprint.

Abstract

This paper discusses the design, construction, and testing of a water flow control and monitoring system in pipes that aims to detect leaks and combine water flow in real time to improve efficiency and reduce potential losses due to leaks. This system is designed using water flow sensors placed in each channel in a certain number to detect the air flow rate. The difference in air flow read from several sensors is used as an indication of a leak. This system is integrated with a microcontroller and is equipped with control via an electric solenoid valve that allows for leak handling and air flow diversion when needed. Several tests have been conducted to ensure the system is ready for use, and the results show that the system is able to control air flow well without any problems, and is able to monitor air flow in real time, detecting changes in flow when a leak occurs. This research contributes to a device for controlling and monitoring water flow in pipes to improve the efficiency of water channel handling
