Intelligent shoe cabinet system based on multiple sensors

With the acceleration of modern life, the quality and safety of shoe storage have become increasingly important. This article introduces a smart shoe cabinet system based on multiple sensors, aiming to improve the environmental quality of shoe storage. The system uses STM32F103C8T6 microcontroller to achieve the main control function. It utilizes infrared photoelectric sensors, air quality sensors and temperature and humidity sensors to achieve automatic detection and control of ammonia, dust, and temperature and humidity in the cabinet. When ammonia, humidity, and dust concentration exceed the standard, the system can automatically operate the ventilation and purification device to avoid odors. The system also has an automatic backlight function. It uses an infrared sensor to detect the status of the cabinet door. When the cabinet door is open, it can automatically execute the backlight function, making it easy for people to choose their favorite shoes. Experimental results show that the system can effectively improve the environment inside the shoe cabinet and enhance the quality of stored shoes.
