Creating and Evaluating Effectiveness of Smart Egg Rack

Abstract

The objectives of this project were to create and develop a smart egg tray, evaluate its performance, and study user satisfaction. The population consisted of people aged 25–50 years who worked outside the home or elderly people living alone and had smartphones with Internet access. A sample of 30 participants was randomly selected. The developed device and system were designed based on system analysis and development principles. Internet of Things (IoT) technology was applied, while PHP, Bootstrap, and C++ were used to develop a responsive system supporting various devices. The system consisted of two parts: the administrator and user modules. After development, the system was tested for effectiveness with 30 participants for two weeks, from January 11 to 25, 2020. The data were analyzed using mean and standard deviation.

The results showed that the overall efficiency of the smart egg tray, including the device and system functions, was 90.17%. Users were highly satisfied with the developed system (x̄ = 4.19, SD = 0.65). The smart egg tray could notify users via the LINE application when the number of eggs was low, allowing them to purchase eggs conveniently. Users could also check the remaining number of eggs and monitor average egg consumption accurately. The system provided information on daily and weekly egg consumption, offering greater convenience to users. Moreover, it facilitated the monitoring and care of elderly people living alone, particularly those under the supervision of family members or caregivers.
