ABSTRACT
With the continuous improvement of modern living standards, traditional shoe cabinets face persistent problems such as moisture-induced mold, odor accumulation, and bacterial growth, which have become critical concerns for household health management. This project focuses on the development of an intelligent drying shoe cabinet system, aiming to provide a comprehensive smart storage solution through the synergy of hardware and software innovations.Hardware Design:The system employs a DHT11 humidity sensor for real-time monitoring of internal cabinet humidity, automatically activating PTC heating elements and silent fans for rapid dehumidification when thresholds are exceeded. An MQ-135 ammonia sensor precisely detects odor concentrations, triggering dual-action purification via UV sterilization lamps and activated carbon fans. An infrared obstacle avoidance module enables automatic door opening upon human approach, with a servo motor ensuring smooth cabinet door operation. An OLED display provides real-time visualization of key parameters including humidity and ammonia levels, offering an intuitive user interface.Software Design:Powered by the STM32F103C8T6 microcontroller, the system implements intelligent control logic with real-time environmental parameter monitoring, threshold-based decision making, and device coordination. The RTC module supports scheduled operation intervals with automatic energy-saving during off-hours. WiFi connectivity enables remote monitoring via a mobile application, allowing users to adjust thresholds and manually activate dehumidification/odor removal functions from anywhere.Performance Verification:Physical testing confirms the system achieves 60% improved dehumidification efficiency, 99% sterilization rate, and over 90% odor elimination. These results effectively address traditional shoe cabinet challenges while providing households with an intelligent, health-focused storage solution. The system demonstrates significant market potential and broad application prospects for modern smart home environments.
