Design and Implementation of a Solar Panel Tracking and Protection System Using Arduino and Sensor Integration
Abstract
This paper presents the design and implementation of a single-axis sun tracking and protection system aimed at improving the efficiency and longevity of photovoltaic (PV) panels. The system utilizes Light Dependent Resistors (LDRs) and airflow sensors to adjust the orientation of the PV panels, ensuring they are always positioned to face the direction of maximum solar irradiation. This alignment optimizes energy absorption, thus enhancing system performance. Additionally, the system incorporates a protective feature that adjusts the panel orientation in response to harsh winds. By aligning the panels parallel to the wind direction, the system minimizes potential damage to the PV modules.
The algorithm governing the system operates in two modes: solar tracking and solar protection. Under normal weather conditions, the system prioritizes solar tracking, continuously adjusting the panel orientation to maximize sunlight exposure. However, when the system detects the onset of strong winds, the algorithm switches to the protection mode, temporarily halting solar tracking and repositioning the panels to mitigate wind damage.
This paper elaborates on the design principles, sensor integration, and algorithm development behind the system. It also discusses the potential benefits of combining sun tracking with environmental protection, leading to improved efficiency during favorable weather and enhanced durability under extreme conditions. The system aims to provide a sustainable solution for optimizing PV performance and safeguarding panels in varying environmental scenarios.

Development and Implementation of an Online Attendance Management System: Advancements, Benefits, and Challenges
Abstract
The Online Attendance Management System is a web-based application designed to simplify and automate the process of tracking and managing attendance in educational institutions, organizations, or events. Traditional methods of attendance management are often time-consuming and prone to errors, which this system aims to address. It offers an efficient, user-friendly solution for recording and monitoring attendance, featuring real-time updates, role-based access, and automated reporting.
This system enables instructors, administrators, and students to interact with a centralized platform, where teachers can mark attendance manually, or through biometric or QR code scanning. Key features include leave management, attendance analysis, and automated notifications for both students and staff. The system also provides a secure database for storing and retrieving attendance records, ensuring the integrity and privacy of the data.
By incorporating modern technology, the Online Attendance Management System eliminates the need for paper-based registers, reduces the risk of human error, and ensures that attendance data is always up-to-date and easily accessible. This solution enhances the efficiency and accuracy of attendance tracking, making it an ideal tool for both educational institutions and businesses.

Impact of Industrialization on River Water Quality in Jharkhand: Causes and Consequences
Abstract
Jharkhand became the 28th state in India in year 2000. Because it possesses so many minerals, it has become an important industrial centre. However, the water quality in its rivers has gotten a lot worse because industry has grown so quickly. The essay looks at the different ways that industrial growth and river water pollution are linked in Jharkhand. It looks at the main causes, which include mining, making steel, generating thermal power, and poor waste management systems. The study combines what we now know about pollution sources, water quality indicators, and environmental effects, and it also points out problems with present efforts to reduce pollution. The results show that the quality of water in important rivers like the Damodar, Subarnarekha, and Kharkai has gotten much worse, which is bad for both ecosystems and people's health. The evaluation ends with suggestions for better rules and more environmentally friendly company practices to deal with this big problem for the environment.
