    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.

    Development of Energy-Efficient Smart Switch and Lighting System
    (ICSSD 2024, 2025) Usikalu, M. R.; Okogbue, S. C.; Ogunwale, E. I.
    The need for better security measures in controlling access to vital utilities bring about the high demand for smart home systems. In this project a smart switch and socket system was developed using the ESP8266 microcontroller and the Blynk application as wireless control. The main goal is to design and implement a cost-effective system that ensures dependable remote control and monitoring of electrical devices. The project provides a functional prototype capable of managing device states and enabling power cut-off for safety especially in school environments, to enhance child safety by adding the ESP8266 with relay modules. The Blynk app was used which facilitates effective monitoring and control of various electrical loads. Effective monitoring and control of various loads was facilitated by the Blynk app. The results showed that the microcontroller’s response time in putting on relay 1 and putting off relay 2 respectively were 1.2 and 1.1 seconds. In case when the load exceeds the safe limit, it ensures power cut off enhancing the safety and reliability
