In the quest for efficient power distribution, this article explores the design and implementation of a smart three-phase electrical panel that seamlessly integrates Internet of Things (IoT) technology. The core of this innovation lies in the utilization of NodeMCU, coupled with Blynk platform connectivity, providing users with unprecedented control and monitoring capabilities. Alongside IoT functionality, the panel incorporates a manual push button for localized control and a photocell sensor, linked to a contactor for intelligent lighting management based on ambient conditions. The article delves into the intricacies of the design, outlining the components, implementation steps, and the dual modes of operation – online mode for remote control and offline mode for local functionality. The presented smart panel not only marks a significant advancement in power distribution but also serves as an example for the future of intelligent electrical systems.

A developing country's economic interest is to determine when its national income approaches that of developed nations. The availability of energy, natural resources, and geographic location are important factors in this. Renewable energy appears to be the answer of the future, while traditional electricity sources like gas and oil are scarce, costly, and harmful to the environment. Pakistan has the ability to meet its electricity needs, addressing issues like power shortages, pollution, and high production costs. The country is strategically located and has an abundance of renewable resources. If this potential is fully realized, Pakistan might even start exporting electricity. Although the nation has started wind, solar, hydroelectric, and bioenergy projects, tidal energy is still mainly unexplored. Recent research provides evidence for the consideration of tidal energy as a potential renewable source for Pakistan's energy needs. The exploration and utilization of these renewable resources not only address the energy needs of Pakistan but also contribute to global efforts in adopting sustainable energy practices. Efforts towards harnessing tidal energy in Pakistan should be intensified, especially along the coast where natural tidal lagoons are prevalent. In-depth surveys and thorough investigations are crucial, particularly in the creek regions of Sindh province.
