Kamrul; Alam, Md. Tawhidul Abstract: This capstone project presents the design, development, and evaluation of the "Next-Gen Easy Bike with Efficient Solar and IoT-Based Navigation System," which aims to revolutionize urban transportation in Bangladesh through sustainable technology integration. Addressing challenges such as dependency on unreliable grid electricity, limited charging infrastructure, and environmental concerns, the project is equipped with a Solar Panel, a Maximum Power Point Tracking (MPPT) charger, and an IoT-enabled innovative navigation system. The innovative system maximizes solar energy capture using MPPT algorithms and a DC-DC boost converter, supported by a hybrid charging approach that integrates grid electricity to ensure reliability under variable weather conditions. IoT capabilities enable real-time location tracking and ensure the safety of the easy bike. Extensive simulation and hardware implementation validate the design’s technical feasibility, demonstrating significant improvements in energy autonomy, operational cost reduction, and environmental impact compared to conventional grid-dependent Easy Bikes. Economic analyses reveal a favorable cost-benefit profile with a short payback period, making the solution accessible to low-income users and scalable for broader deployment. The project multidisciplinary framework combines mechanical, electrical, and socio-economic factors essential for adoption in developing regions. In conclusion, this approach provides an effective, eco-friendly, and affordable solution that supports sustainability goals worldwide and creates a strong base for future growth in renewable energy and smart transportation.

Md. Farhanul; Alam, Mohammad Tawhidul Abstract: An IoT-based solar-powered water purification and monitoring system is presented in this project work as integrated, autonomous, and efficient systems that can supply clean water. This research presents an approach to water purification by integrating Internet of Things (IoT) technology with solar energy to create a sustainable solution. The system comprises a water purification unit equipped with filtration and disinfection mechanisms, powered entirely by solar panels. The IoT framework enables real-time monitoring and control, ensuring optimal performance and user-friendly interaction. The solar energy subsystem harnesses sunlight through photovoltaic panels, storing excess energy in batteries for uninterrupted operation during low-light periods. A microcontroller is used as the system's central hub in this project. It communicates with various sensors, like as pH Sensor, Total Dissolved Solids (TDS) sensor, turbidity sensor, and temperature sensor. It measures water quality parameters and oversees the energy balance within the system. The collected data is transmitted to a Google sheet platform for storage and analysis. A user-friendly interface, accessible through a mobile app or web dashboard, allows users to monitor water quality metrics, system status, and energy levels. The system generates alerts for potential issues, providing users with timely notifications for maintenance or adjustments.

Supermarkets provide a large variety of things, including fresh vegetables, meats, dairy, and packaged goods, as well as home essentials, making them an excellent one-stop destination for completing all shopping at once. This convenience, however, is not without its drawbacks. Long lineups can make shopping experiences unpleasant, leading supermarkets to utilize techniques such as technological improvements to enhance the shopping experience—especially during peak periods when many offers are available. The billing method is typically time-consuming and hectic, requiring the inclusion of more human resources in the billing area. Customers often have trouble operating excessively loaded carts. Manual computations of purchases and budget comparisons until the scanning process in the invoicing area add another degree of aggravation. To address these concerns, an extraordinary idea encompassed with IoT and RFID scanners are implemented into shopping trolley. As clients load items into the trolley, the RFID reader automatically reads product data such as item names, prices, and weights. A speaker will declare the goods that buyers have chosen, as well as their price and weight. This information is then shown on a screen, allowing buyers to inspect goods and alter pricing by rescanning. Furthermore, the trolley is designed to move, eliminating the need for customer to push it back and forth. Customers may pay with cards while shopping by simply putting the card in front of the RFID, and the payment is completed in seconds. An SMS will be delivered to the customer's phone number to confirm the payment, and the payment procedure will also trigger an announcement over the speaker if the card does not have an adequate balance. When a customer is done shopping, they can easily take their cart to the payment area. This cuts down on the time-consuming physical counting process and makes shopping less tiring, especially for older customers.
