Numerous factories, commercial establishments, and private residences require an uninterrupted power supply. The primary source of this supply is often the grid. Industries, businesses, and residential areas needing 24-hour power inevitably require backup systems to ensure continuous operation of essential electronic devices. Typically, diesel generators are employed as backup power sources, utilizing diesel oil to generate electrical energy. While this approach has been successfully employed for many years, it carries a significant drawback. Diesel oil falls under the category of non-renewable energy sources, unable to be regenerated and requiring an extensive period for renewal. Furthermore, diesel generators emit substantial amounts of carbon dioxide into the atmosphere, contributing to air pollution in the vicinity. To address these challenges, a prototype implementing a smart Internet of Things (IoT) approach has been developed. This study introduces the utilization of an Arduino Nano microcontroller, allowing users to control their power supply source, choosing between the grid, solar panels, or water generation. This control process is facilitated through a smartphone application, granting users the ability to manage it remotely, enhancing monitoring capabilities. The system incorporates two environmentally friendly power sources: solar panels and a mini water turbine, both considered safe for ecological balance. The outcomes of this research demonstrate that users can effectively utilize the generated electricity supply for approximately 12 hours, thereby reducing reliance on the grid and harnessing the potential of renewable energy sources.
