Li-Fi, a wireless communication technology utilizing light signals, offers numerous advantages over traditional radio frequency-based methods, including higher data rates, reduced electromagnetic interference, and enhanced security. Leveraging the unique properties of Li-Fi, such as its ability to transmit data through light waves, this study investigates its potential application in audio signal transmission. Through experimental analysis and theoretical considerations, we demonstrate the feasibility and efficacy of Li-Fi for delivering high-quality audio signals in various scenarios. Our findings contribute to advancing the understanding of Li-Fi technology and its potential role in shaping the future of wireless audio communication.</p>2024-03-16T00:00:00+00:00Copyright (c) 2024 Authorshttps://journal.hmjournals.com/index.php/JEET/article/view/3905Harnessing Plant Bioelectricity through Prickly Pear as Botanical Batteries2024-03-22T05:30:48+00:00Rhean Jane B.

HinacayHinacay.ja@gmail.com<p>Plants which are essential for life, have the potential to become a renewable energy source in the Future. They can generate electricity, reducing greenhouse gas emissions and being environmentally friendly. This study aims to explore the untapped potential of botanical batteries and contribute to green energy technology. Plants' capacity to convert sunlight into chemical energy could be a viable and environmentally friendly source for electrical power generation, offering a sustainable solution to the world's growing energy demands while mitigating climate change impacts.</p> <p>To achieve the goal of the study, pure experimental research was applied. And the researchers used cactus (prickly pear), copper nails, zinc nails, copper wire, alligator clips, and disposable plastic containers. The study was conducted at Bayugan National Comprehensive High School, Bayugan City.</p> <p>Throughout the analysis of the data obtained after the three tests conducted, it has been found that like an electrochemical cell, copper and zinc electrodes inserted into prickly pear leaves can generate energy. With the highest current magnitude and maximum value at the highest contact area, the prickly pear plant has the highest potential for energy harvesting. Cut-off or partially leaved leaves can be harvested for their energy, which can then be utilized to charge batteries or power low-power devices.</p>2024-03-21T00:00:00+00:00Copyright (c) 2024 Authorshttps://journal.hmjournals.com/index.php/JEET/article/view/3947A Comprehensive Survey on Semi-Automatic Solar-Powered Pesticide Sprayers for Farming2024-03-28T10:20:44+00:00Dr. Altaf O. Mulanidraomulani.vlsi@gmail.com<p>In recent years, the agriculture sector has witnessed a growing demand for sustainable and efficient pest management solutions to enhance crop yield and reduce environmental impact. Among these solutions, semi-automatic solar-powered pesticide sprayers have emerged as promising tools for farmers worldwide. This paper presents a comprehensive survey of semi-automatic solar-powered pesticide sprayers designed for farming applications. The survey begins by exploring the motivations behind the development of solar-powered pesticide sprayers, emphasizing the need for environmentally friendly alternatives to traditional pesticide application methods. It proceeds to examine the key components and functionalities of these sprayers, including solar panels, rechargeable batteries, pumps, nozzles, and control systems. Special attention is given to the integration of solar energy harvesting mechanisms and their impact on operational efficiency and sustainability. Furthermore, the survey investigates the design considerations and technical challenges associated with the development of semi-automatic solar-powered pesticide sprayers. Topics such as system autonomy, spray coverage, pesticide dosage control, and user-friendly interfaces are thoroughly discussed. Additionally, the paper highlights recent advancements and innovations in the field, including the incorporation of smart sensors, GPS technology, and data analytics for precision spraying and monitoring.</p>2024-03-28T00:00:00+00:00Copyright (c) 2024 Authors
