Automatic Rain Sensing Car Wipers

Abstract

Traditional car wiper systems often operate at preset intervals or manual controls, leading to inefficiencies during varying weather conditions. The development of automatic rain-sensing car wipers addresses this challenge by leveraging sensor technologies and automation to enhance safety and convenience for drivers. The problem lies in inefficient and inconvenient manual control of windshield wipers during varying weather conditions, particularly wiper systems that rely on preset intermittent settings or manual adjustments, which may not always match the intensity of the rainfall in real time. This can lead to suboptimal visibility, compromising driver safety, and overall driving experience. This project aims to mitigate these issues by implementing an automatic rain-sensing mechanism. Research objectives include designing a robust sensor system capable of accurately detecting rainfall intensity and adjusting wiper speed accordingly. The research methodology used for this project is gathering information, sensor selection and integration, coding development, prototype development, evaluation and testing. Findings reveal that automatic rain-sensing car wipers significantly improv e visibility and driver safety while optimizing wiper blade lifespan and energy consumption. However, certain limitations such as sensor accuracy in extreme weather conditions may require further refinement. Improvement suggestions include fine-coding rain sensor sensitivity for more precise rain detection. Overall, the project contributes to the evolution of automotive safety and driving efficiency through intelligent wiper systems.
