With the advancement of computers such as Arduino, innovation is reaching the ground level with its application in farming and aquaculture. In this work, we designed and implemented aquaculture water quality monitoring using Arduino. A smartphone, different sensors (Temperature, pH, TDS etc.) and IP camera are used in this work. Arduino is in charge of sensor acquisition. It also serves as a data processing device and a server. Microcontroller also does photo acquisition with the help of the ESP32 camera to detect and ensure security. A user can monitor the water condition using an android app via BT Module and Wi-Fi connectivity. The three parameter values are analyzed to ascertain the overall estimated state of the water and the necessary action. Every function of this testing device is authentic and simple to use thesis 2024-02-05T00:00:00Z http://dspace.daffodilvarsity.edu.bd:8080/handle/123456789/15319 An On Grid Wind Turbine Power Plant Model and Simulation For A Particular Location in Bangladesh Chowdhury, Swarna Mitra; Islam, Rifah Tasnim Wind energy is a renewable resource that Bangladesh has, and we should try to use it to meet the country's electricity needs. As a clean energy source, wind power has great potential to contribute to Bangladesh's sustainable development goals. This article gives a thorough analysis contrasting the viability of wind turbine power systems for power generation in a particular area in Bangladesh, as part of the search for sustainable and renewable energy alternatives. Seven different places were looked at to determine which was the most effective. We chose Teknaf as the target area because of its distinctive geographic and climatic features. The HOMER Pro software is used in thestudy to carry out accurate simulations and economic analyses. The findings show that wind turbines have a greater potential for generating electricity in Teknaf. This area holds high wind speed, especially during specific months of the year, this is the reason for this result. Including installation costs, maintenance costs, and energy output over time are taken into consideration in the simulation and economic analysis. We calculated the economic analysis for the 25-year lifespan of the project at a 50-meter height and assumed about a 10MW load. Our proposed system can generate more than5810MW of electricity every year. The results imply that wind energy systems help achieve sustainable energy goals and that wind turbines offer an efficient and economically feasible choice for generating power in Teknaf.

With a focus on reducing reliance on fossil fuels and mitigating greenhouse gas emissions, the proposed system integrates renewable energy solutions into agricultural practices. The core components, including the PV array, boost converter, and three-level voltage source converter (VSC), are carefully developed to optimize energy transfer and power generation. A maximum power point tracking (MPPT) algorithm is employed to extract the maximum power from the PV array, while smart control mechanisms ensure efficient power utilization and seamless grid integration. The simulated performance analysis under varying solar irradiance and temperature conditions demonstrates the system's robustness and effectiveness. The research aims to promote the adoption of renewable energy-based solutions in agriculture, fostering sustainable practices and contributing to a greener future for farming.

The main goal of the project is to capture the maximum amount of light from the sun and convert it to electricity so that it can be used and moved with ease. By positioning the solar panel such that it faces away from the sun's beams, this interaction should be achievable so that even the strongest daylight may be converted into electricity. Because of this system's incredibly high efficiency. This tracker's main feature is its independence from the sun's energy. It adjusts itself as suggested by that by taking the sun's coordinate directly in accordance with its position. Additionally, it provides improved dependability and efficiency. The advantages of In order to extract the optimal power from solar radiation, the investigation article describes the planning of a cost-effective sun position global positioning framework. The AVR atmega8L microcontroller, an advanced device, forms the basis of the present system. A dedicated board is envisioned to track the location of the sun. The board consists of two photodiodes that are arranged in a standard manner. The location of the sun is determined by gradually contrasting the output of two photodiodes. The program is developed in Code Vision AVR's IDE and then ported to the intended target device. The Sun's rays are predicted to move from east to west as the globe rotates, with the resulting sensor modifications. Two sensors collect basic signals, which are then digitalized and evaluated. The direction of the pivot is determined by the correlation's outcome. evaluated. The direction of the pivot is determined by the correlation's outcome. thesis 2024-01-22T00:00:00Z
