Design and Implementation of a Humidity-Based Corrosion Risk Monitoring System for Aircraft Structures

The project successfully presents the development of a humidity-based corrosion risk detection system using an Arduino microcontroller and a DHT11 sensor. The system continuously monitors environmental conditions and accurately detects variations in humidity levels, which are a major factor contributing to corrosion in aircraft structures. By comparing the sensed humidity with a predefined threshold value, the system effectively differentiates between safe and corrosion-prone conditions. When the humidity level exceeds the threshold, the system immediately activates visual and audio alerts, ensuring quick identification of potential risk. The experimental results and data analysis clearly demonstrate that as humidity increases, the probability of corrosion also increases. This validates the effectiveness of the system in providing early warning signals, which is essential for preventive maintenance in the aviation industry. The implementation of such a system can help reduce unexpected structural damage, improve operational safety, and minimize maintenance costs by enabling timely action before severe corrosion occurs. In addition, the project highlights the importance of real-time environmental monitoring compared to traditional periodic inspection methods. While conventional techniques may fail to detect early-stage corrosion conditions, this system provides continuous monitoring and immediate response, making it more efficient and reliable. Although the current model focuses only on humidity-based detection, it establishes a strong foundation for future improvements. Further enhancements can include the integration of additional sensors such as temperature and corrosion-specific sensors, as well as advanced technologies like Internet of Things (IoT) and Artificial Neural Networks (ANN) for intelligent prediction and remote monitoring. These advancements can transform the system into a fully automated and smart corrosion monitoring solution suitable for real-world aircraft applications. Overall, the project successfully demonstrates a simple, cost-effective, and efficient approach to detecting corrosion risk at an early stage. It emphasizes the significance of preventive maintenance and showcases how embedded systems can be effectively used to improve the safety, reliability, and lifespan of aircraft structures
