Power Factor Improvement Monitoring using IoT Shahin, Md. Saifudin Energy conservation plays a significant role in this environment to save more energy. It thus presents the system that continuously transmits data on the various factors affecting the inductive and capacitive loads onto a webpage via the Internet of Things. It sends alert messages to the concerned person and activates an electronic relay if a defect is detected. The power factor decreases as the inductive load increases, so this system has a power factor improvement mechanism that switches capacitor banks when the inductive load increases. Power Factor Improvement Monitoring will be developed for variable loads to monitor energy consumption and automatically improve their power factor. Additionally, a low power factor will help to reduce the penalty and protect inductive loads as well as identify problems before they arise.

Automatic Electrical Load Control And Monitoring System Hossain, Ashraful This extension aims to collect more electrical data, including the buyers' control use and current, and deliver these real-time values across the network. This project also includes a relay that will switch the electrical circuits use load; when the electrical loads do not need to be used, the relay turns off the load. Substation mechanization has become a prerequisite for each utility firm as the dissemination arrangement has become more modern. It is crucial to understand the urgency that has occurred to advance the quality of power when the security, monitoring, and control of a control system is inadequate. With the help of the current sensor, this system can routinely update electrical characteristics in real time. Although a microcontroller is utilized in this project, we have used an ESP-8266 microcontroller for demonstration reasons because it is a prototype of the suggested concept. The controller must be able to connect to a Wi-Fi network and be able to interact with the computer quickly. When we turn on the control for our model, all of the sensors start to detect current and provide real-time data to the server and the user interface of the app. All current values are stored in Firebase data storage. If the issue continues for the specified amount of time, the relay separates the loads from the rest of the system. In the meantime, the comparison is carried out as already, and transfers are utilized to re-connect the loads to the rest of the framework when the issue settle

Electricity Generation Using Gravity Battery Karmokar, Krisna This project explores an innovative and sustainable method of electricity generation using a gravity battery system. The concept is based on storing energy in the form of gravitational potential energy by lifting a mass to a certain height and converting it back into electrical energy as the mass descends. When excess energy is available, it is used to elevate a heavy object, and during periods of demand, the stored energy is released by allowing the object to fall, driving a generator to produce electricity. The gravity battery system offers a clean, renewable, and efficient alternative to conventional energy storage technologies such as chemical batteries. It reduces environmental impact, requires minimal maintenance, and has a longer operational lifespan. This project highlights the working principles, design considerations, advantages, and potential applications of gravity-based energy storage, particularly in supporting renewable energy sources like solar and wind power. Overall, gravity batteries present a promising solution for sustainable energy storage and contribute to the development of eco-friendly power generation systems.

Design And Implementation of Rfid Based Highway Toll Collection System Rahman, Rejaur The Smart Toll Management System is an advanced automated toll collection system designed to reduce traffic congestion, save time, and improve transportation efficiency. The system uses RFID technology to identify vehicles automatically at toll plazas without requiring vehicles to stop for manual payment. Each vehicle is equipped with an RFID tag that stores vehicle information, and the toll amount is deducted automatically according to the vehicle type. A GSM module is integrated into the system to send instant SMS notifications to vehicle owners after each transaction, ensuring transparency and preventing extra charges. The proposed system also includes a weight sensing mechanism to detect overloaded vehicles and prevent them from crossing bridges or highways, helping reduce the risk of accidents and structural damage. All transaction data is stored in a central database for monitoring and management purposes. Cashless payment and automated processing minimize human error, reduce corruption, and increase government revenue collection efficiency. This project provides a secure, reliable, and low-cost solution for modern toll management, especially suitable for Bangladesh and other developing countries. In addition, the system helps reduce fuel consumption, air pollution, and noise pollution caused by long waiting times at toll booths. The implementation of vehicle registration and RFID-based authentication also enhances security and supports anti theft monitoring. Overall, the Smart Toll Management System offers a fast, transparent, and user-friendly approach to intelligent transportation management.
