    Development and Performance Evaluation of Portable water cooling system using thermoelectric peltier modules
    (ICSSD 2024, 2025) Adeniji, A. P.; Sule, Rasidi; Ogunwale, E. I.; Ayara, W. A.
    High global temperatures have increased the occurrence of heat waves in most parts of the world, and this has increased the utility cost as more cooling devices are being produced for adaptation. This study deals with the performance evaluation of a portable water-cooling system using thermoelectric peltier modules. The experimental setup involved measuring the temperature reduction of water samples for different volumes (500 ml, 750 ml, and 1000 ml) over 60 minutes at equal interval. The peltier module TEC1-12706 was used with voltage of 12 V. The heat sink was used to enhance the absorbed heat transfer in the system while Arduino Uno serves as the central control unit. Results showed that effective temperature reductions were achieved with cooling capacities (Qc) for different volumes of water. The system coefficient of performance (COP) ranges from 0.12 to 0.13.

    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.
