| dc.description.abstract | The advancement of embedded systems and smart automation technologies has created new
opportunities for improving conventional household appliances. This thesis presents the design
and implementation of a smart refrigeration system capable of real-time temperature monitoring
and automated cooling control. The proposed system integrates an ESP32 microcontroller,
DS18B20 digital temperature sensor, relay module, LCD display, and wireless communication
technology to enhance the functionality and efficiency of a refrigerator.
The system continuously monitors the internal temperature of the refrigerator and displays real
time information through both an LCD display and a web-based interface. Based on user-defined
temperature settings, the controller automatically activates or deactivates the compressor using a
relay module to maintain the desired cooling condition. The design also allows users to control
the refrigerator and adjust temperature settings through physical buttons or a mobile device
connected via Wi-Fi.
The developed prototype emphasizes reliability, ease of implementation, and energy-efficient
operation. Experimental observations demonstrate that the system can accurately maintain the
required temperature range and respond effectively to internal temperature variations. The
integration of embedded control and wireless monitoring significantly improves user
convenience and refrigeration performance compared to conventional systems.
The proposed smart refrigeration system provides a practical and affordable solution suitable for
household, laboratory, commercial, and pharmaceutical storage applications. Furthermore, this
research establishes a foundation for future developments such as IoT-based cloud monitoring,
intelligent food management, and advanced energy optimization techniques. | en_US |
