(International Journal of Environmental Engineering and Development Vol 2, 2024) AKINWUMI, Sayo A.; OSCAR, Blessing N.; MASTORAKIS, Nikos E.; AYANBISI, Oluwasegun W.; OLADAPO, Olutade F.; OGUNWALE, Emmanuel I.
The construction of a biogas digester is the ma in emphasis of this project. Biogas is a mixture of gases created during the anaerobic decomposition of organic material, including food waste, animal waste, sewage, and waste from farms and plants. One of the major causes is environmental degradation, which has emerged to be the greatest threat to the health of the environment and the economy of the underdeveloped areas. But with the discovery and application of biogas which is a gaseous fuel obtained from biomass by the process of anaerobic digestion, most problems are resolved. The project’s aim is to create a biogas digester that leverages animal manure to generate biogas for usage at Covenant University. The digester selected for construction is a barrel drum digester for the production of biogas using cow dung. The cow dung was tested for a total of 14 days, during which the days of gas production and digestion were observed, and the biogas was then tested with the gas and temperature sensor and was confirmed to detect gas and temperature.
Construction of an Arduino Based Smart Energy Meter
(ICSSD 2024, 2025) AKINWUMI, Sayo A.; Braide, S. M.; Arijaje, T. E.; Akinwumi, O. A.
The design of a smart energy meter with an arduino that measures the current, voltage, energy and power by an individual or small organization is very important. Electricity is among the basic requirements for the maintenance of life contents. But in our country, we have many localities where they have constant electricity and others with little or no access to electricity. Consumers are dissatisfied with the services been provided by the electricity company, and the absurdity in monthly bills are the most common source of displeasure. The issue of having outrageous bills despite the lack of electricity, the ignorance of how much voltage and current is being used in homes led to this creation of this project. This focuses on the system’s problem which entails workforce, time consumption and manipulations of readings by an official authority while producing the bill to the consumer. This project consists of the following components Energy Meter, Arduino DANO Board, Global System for Mobile Communications (GSM) Module, Capacitor, Mobile Phone, Load, Current sensor acs712, Voltage sensor, Transformer, Vero Board, and liquid crystal display (LCD). The energy meter continually monitors the readings and the Arduino processes this data and the readings are uploaded on the liquid crystal display (LCD) of the device and when the readings are taken the Global System for Mobile Communications (GSM) module posts the readings to the thingspeak on the mobile phone. The constructed device displayed the energy, power, current and voltage been consumed with varying loads used and the readings were uploaded on the platform used (thingspeak). The results shows that at 153 W it was at its highest point and at 132 W it was at the lowest point when plotted with time. From the results, it shows that the device is working perfectly. There was fluctuation in the power, voltage and currents but constant increase in the energy. Asides from the saving of cost in relation to remote reading of meters, it is hoped that implementation will encourage energy efficiency and raise awareness of energy consumption and demand side participation in the national energy market. This project is recommended for the electricity power company (PHCN) and it is also recommended for individuals that reside in some localities because it would help save cost and it is convenient.
Eco-friendly Weather Monitoring Device using Arduino Mega and Sensor Integration
(ICSAEES-2024, Lagos, Nigeria, 2024) AKINWUMI, Sayo A.; Okey-Amadi, O.; Ayara, W. A.; Akinwumi, O. A.
The project involved the construction of a hardware setup, utilizing the Arduino Mega as the central control unit. The BME280 sensor was employed to monitor temperature, humidity, and atmospheric pressure, providing comprehensive weather data. The SGP30 sensor was utilized for analyzing air quality, detecting various pollutants such as volatile organic compounds (VOCs) and carbon dioxide (CO2) levels. The MQ135 gas sensor enabled the detection of harmful gases, including ammonia, nitrogen dioxide and benzene. The integration of a 16x4 LCD display allowed for real-time visualization of the collected weather data, providing users with immediate insights. Tactile switches, along with 10k ohm resistors, were used for user interaction, enabling menu navigation and system control. The DS1302 RTC module facilitated accurate timestamping of data readings, while the SD card module enabled data logging for long-term analysis and storage. The successful construction of the Weather Monitoring System demonstrated its capabilities in terms of accuracy, reliability, and real-time monitoring. The integration of Arduino Mega, along with the BME280, SGP30, MQ135, LCD display, push buttons, 10kohm resistors, DS1302 RTC module, and SD card module, provided a comprehensive solution for weather data collection, analysis, and visualization. This project contributes to the advancement of weather monitoring systems, emphasizing the importance of Arduino-based solutions and sensor integration. It highlights the potential for utilizing such technology to address weather challenges effectively, enabling datadriven decision-making and fostering weather awareness. Overall, the Weather Monitoring System presented in this project report offers a valuable tool for monitoring and analyzing atmospheric conditions, paving the way for future enhancements and applications in various weather monitoring domains.
