Automatic Shoe Drying Cabinet

Abstract

The Automatic Shoe Dryer Cabinet project was developed to address the common problem of damp footwear, unpleasant odours, and microbial growth caused by ineffective traditional drying methods. Conventional sun-drying is slow and inconsistent, especially during rainy weather. This project aims to design and evaluate an IoT-based shoe drying system that automatically regulates temperature and humidity to ensure faster, safer, and more efficient drying.The system incorporates an ESP32 microcontroller, DHT11 temperature–humidity sensor, DC fan, and heating lamp. Through real-time monitoring via the Blynk mobile application, users can observe environmental conditions and control the cabinet remotely. Experimental testing was conducted on sports shoes, leather shoes, and slippers. Results demonstrated that the system successfully maintained stable drying temperatures (43–45°C), reduced humidity to below 50%, and shortened drying time by 50–60% compared to natural air drying.In conclusion, the developed prototype achieved all project objectives by providing an effective, energy-efficient, and IoT-enabled shoe drying solution suitable for modern households. The system has strong potential for commercialization as a smart home appliance.
