Light Dependent Resistor Sensor Used for Optimal Power Consumption for Indoor Lighting System

Abstract

Electricity had become one of the most essentials in life. The need for electricity keeps increasing. It has become a challenge to maintain this service evenly to everyone around the world. The high demand and the consumed power bring negative feedback due to the lack of natural resources and have a high impact on global warming. Hence, this paper is built to optimize electrical power consumption. The research of the optimum energy consumption and utilization control system works based on proposed goals. The working principle is interfacing among the Light Dependent Resistor (LDR), Global System of Mobile (GSM), bulbs, and Arduino board. LDR works according to the surrounding environment, while the GSM depends only on the user's order for the ON/OFF functions. The obtained results and calculations have shown that this system can save much electrical power consumption during the day. The essential factor for the bulb light intensity depends on the external light source; therefore, it varies according to the climatic conditions, the season of the year, and the day. The most important in this research is to provide the best and the most convenient lighting system that can easily save electrical power consumption.
