Abstract: Earthquakes and landslides pose significant threats to both humans and animals, often resulting in severe loss of life and property. Moreover, the safety of animals near roadways is frequently compromised, leading to accidents and fatalities. Addressing these challenges requires an integrated approach that combines the detection of natural disasters, animal management, and road safety measures. This abstract presents a comprehensive project aimed at developing a state-of-the-art system that can detect earthquakes and landslides, close gates to prevent animal interference, automatically feed roadside animals, and provide alerts for approaching vehicles, as well as the temperature and humidity of that area. The proposed project utilizes modern technologies such as sensors and communication systems to enhance disaster detection, animal management, and road safety. The system collects real-time data from multiple sources, like a gyroscope, to identify earthquakes and landslides promptly. By continuously monitoring seismic activities and analyzing environmental conditions, the system can accurately forecast and evaluate the severity of potential disasters. In the event of an earthquake or landslide, it gives alert to the office. To address the needs of animals near roadways, the system incorporates an automatic feeding mechanism. Equipped with sensors that detect the presence of animals, the system can dispense food at specific locations, attracting animals away from roadways. This feature not only safeguards the animals but also helps prevent vehicle collisions caused by animals wandering onto the road. Additionally, the system closes the gate of that road if any animal comes to it, and it automatically opens if the animal goes away. This provides safety for both humans and animals and avoids accidents. Furthermore, the project focuses on road safety by leveraging advanced technologies to detect approaching vehicles. It uses sensors to detect the vehicle approaching on the opposite side of the mountain hairpin bend. This gives information about the vehicle and prevents more accidents in the hilly regions. The integrated system is designed to be user-friendly and accessible to stakeholders involved in disaster management, animal welfare, and road safety. A centralized control panel provides a comprehensive overview of detected disasters, animal-related activities, and approaching vehicles. Stakeholders can access real-time data, receive alerts, and make informed decisions to mitigate potential risks swiftly and effectively. The project also considers the scalability and adaptability of the system. The underlying architecture is designed to accommodate future expansions and improvements, ensuring its efficacy in addressing emerging challenges. Moreover, the system can be customized according to the requirements of different regions and adapted for deployment in various environmental conditions. In conclusion, the proposed project offers a comprehensive solution to address the critical issues of disaster detection, animal management, and road safety. By incorporating advanced safety of roadside animals, and alerts relevant personnel to approaching vehicles. The integration of these functionalities provides a holistic approach to disaster management, animal welfare, and road safety, ultimately leading to a safer and more resilient environment for both humans and animals alike.

Abstract: The biggest crisis we are heading into is the climate change due to excessive use of fossil fuels and to overcome these issues, we have only one solution that is utilizing Renewable Energy. Renewable energy is a type of energy that is harnessed from the nature without causing ill effects to the environment. One of the most prominent kind of renewable energy is solar energy. Solar radiation from the sun is collected by the solar panels and converted into electrical energy. The output electrical energy depends on the amount of sunlight falling on the solar panel. Traditionally, solar panels are fixed and the movement of sun over the horizon means that the solar panel does not harness maximum energy most of the time. In order to maximize the power from the solar panel, the panel should face the sun all time. In this project, we will make a sun tracking system which will help the solar panels to generate maximum power. In some of our previous articles, we have built simple system to track power generated from solar panel and other solar energy related projects. You can check those out if you are looking for more projects on solar power.
