The design is to place the end of any umbrella handles which is compatible with J-Handle and Foldable type of umbrellas [1]. Utilizing an Arduino Uno microcontroller, a DHT22 temperature sensor, a server fan, and a PTC ceramic heater, the system regulates airflow and drying temperature to accelerate the drying process while maintaining safe operating conditions. Following ASTM D2654 standards to evaluate drying performances of any umbrella types such as Nylon, Polyester and PVC where it achieves fastest drying time averaging 8 minutes for collapsible models and 9.2 minutes for J-handle models [2]. Polyester umbrellas required approximately 15 minutes, while PVC umbrellas dried within 17 to 20 minutes. The temperature ranges from 28°C to 33°C. which were within acceptable safety limits. The developed system provides a practical and energy-efficient solution for minimizing wet floor hazards and improving convenience in indoor environments. Alex James H. Geronimo, John Wayne L.
