Abstract

Malaysia, the climate often fluctuates between extreme heat and sudden heavy rainfall, causing inconvenience for residents who are away from home. To address this issue, this study aims to create a smart clothing drying system using Arduino technology. This system allows for semi-automatic or fully automatic clothes drying, adapting to changing weather conditions. The system's core is an Arduino, which interfaces with sensors measuring humidity, temperature, air pressure, light intensity, UV intensity, and rainfall to gather comprehensive environmental data. This data feeds into a model that evaluates if the current weather conditions are suitable for air-drying clothes. The system utilizes predefined strategies and thresholds to make autonomous decisions about whether to proceed with clothes drying. Arduino controls two DC motors to move the clothes rack to suitable locations, such as indoors during unfavorable weather or outdoors on sunny days. For remote control, Arduino is equipped with Wi-Fi connectivity, enabling a mobile app through the Blynk IoT platform for precise manual adjustments. This app not only offers remote control for retrieving or hanging clothes but also provides real-time sensor data and notifications about clothing rack movements and potential rain. The system incorporates advanced features such as manual remote control of wheel movements, path recording and playback, and reverse path execution. All settings and recorded paths are stored in EEPROM, ensuring persistence across power cycles. Additionally, the system considers sunrise and sunset times to determine its operational hours. This intelligent system provides users with convenient control over clothes drying, whether through automated decisions based on sensor data and predefined strategies or remote manual operations, thus simplifying daily life and improving energy efficiency.
