Abstract: This "Manhole Cover Security and Monitoring System" addresses the issues of theft and vandalism of manhole covers which results in open manholes, and poses a significant safety risk to pedestrians and vehicles. By utilizing a laser light technique and a Light Dependent Resistor (LDR), the system is able to detect the presence or absence of light, indicating whether a manhole cover is open or closed. The functioning of the system is based on the principle that when a manhole cover is in its proper closed position, it blocks the laser light from reaching the LDR. However, if the cover is open or displaced, the laser light falls directly on the LDR, causing it to detect the light. When the LDR detects light, the system is triggered to initiate an alert mechanism. This alert mechanism involves the integration of a SIM800L module, which enables the system to communicate through SMS. Once the LDR senses an open manhole, the system immediately sends an SMS alert to pre-determined recipients, such as relevant authorities or maintenance personnel responsible for resolving the situation. The objective of this design is to provide an efficient and automated solution for detecting and notifying the presence of an open manhole cover, by promptly alerting the appropriate individuals or organizations. The system helps to mitigate potential accidents or hazards caused by open manholes. This contributes to maintaining public safety and preventing injuries or damage to property.

Abstract: The recycling of solar panel cells has undergone a transformative journey, encompassing the past, present, and future of sustainable practices within the renewable energy sector. This abstract explores the evolution of solar panel recycling from its early stages to the current state of the industry and anticipates future trends. In the past, recycling methods were rudimentary, with little focus on the recovery of valuable materials. Today, innovative approaches have emerged, leading to more efficient and environmentally friendly recycling processes. Current methodologies aim to extract and reuse valuable components like metals and polymers while reducing environmental impact. Looking ahead, the future of solar panel recycling will continue to evolve, with ongoing research dedicated to enhancing efficiency, reducing costs, and broadening the range of recoverable materials. As solar energy adoption grows, establishing strategically located recycling centers and adopting sustainable practices will be pivotal for the long-term sustainability of solar technology. This abstract underscores the significance of sustainable practices in the solar industry and their role in maintaining solar power as a clean and renewable energy source for the future.

Abstract: This study explores the use of Arduino to construct a fingerprint authentication voting system in order to improve electoral security and efficiency. By incorporating biometric technology, the method guarantees each voter's identification is distinct and verifiable. It reduces the hazards connected with conventional techniques and encourages a more trustworthy electoral process by utilizing fingerprints. In examining the system's technical features, security protocols, and sociological ramifications, the article highlights biometrics' crucial role in preserving democratic norms.
