Eggs are a food ingredient with excellent nutritional value, but their quality can deteriorate when stored for a long time. As consumers, it is crucial to be cautious in determining the quality of eggs to be consumed, as eggs may contain harmful pathogens that can cause diseases. The traditional manual detection process, typically done using a flashlight and water, is time-consuming and not always accurate. To address this issue, there is a need for an accurate egg quality inspection system to ensure that the eggs consumed are in a suitable condition. Based on this problem, an automated egg quality detection device has been developed using a Light Dependent Resistor (LDR) sensor. The device is composed of an Arduino Uno as the main microcontroller. When the LDR sensor detects light intensity emitted from the egg with a value <600, the egg is considered good; conversely, if the LDR value is >600, the egg is deemed bad. The output of the detection process is displayed on an LCD screen, accompanied by indicator lights. This device not only aids consumers in selecting high-quality eggs but also provides advantages for the egg industry. The implementation of this technology can enhance the efficiency of the mass egg selection process, reducing the risk of spreading diseases present in substandard eggs.
