Bharati Laxmi 03 04 Agriculture is greatly affected by changing weather conditions especially unexpected heavy rainfall which candamage crops wash away soil and disturb normal plant growth To address this problem this project introducesan Automatic Rain Activated Shutter System that helps protect crops using a simple and responsive sensorbasedapproach The system uses a rain sensor to detect rainfall and automatically activates motorized shutters orcovers to protect the crop area This immediate response reduces the need for manual work prevents cropdamage and improves overall farming efficiency The system is built using IoTbased components such asmicrocontrollers like Arduino or ESP32 rain sensors and actuators making it affordable and easy toimplement It is especially useful for smallscale farmers and greenhouse environments where quick action isimportant In the future the system can be enhanced by adding weather prediction features and solar powersupport for better sustainability LED indicators are also included to provide clear and simple information aboutthe systems working status ensuring easy and the Smoothoperation Copyright (c) Journal of Science Engineering Technology and Management Science.
