Using a rain sensor, Arduino microcontroller, and servo motor, the system detects rainfall and automatically closes a protective cover to safeguard clothes, thereby preventing them from getting wet. This innovation aims to provide a hands-free solution for protecting outdoor items left exposed to sudden rain showers, improving the efficiency of drying clothes in open spaces. The servo motor moves the protective cover based on the rain signal from the sensor, and when the rain stops, the system opens the cover to allow drying to continue. This paper explores the system's working principle, design methodology, and potential applications, particularly in residential and industrial environments.
