基于单片机的杀菌除臭防潮智能鞋柜设计
摘 要
在当今社会，人们对于居住环境的健康和舒适性日益关注。尤其是鞋柜作为家居生活中常用的物品之一，往往面临着潮湿、霉变、异味等问题，这些问题可能会影响家居环境的质量，甚至对家庭成员的健康构成威胁。此外，一些有害气体如氨气和烟雾也可能在鞋柜内积聚，存在一定的安全风险。本研究旨在设计一种基于STC89C52单片机的智能鞋柜，以实现杀菌、除臭和防潮功能。该智能鞋柜具备以下主要功能：首先，通过DHT11传感器监测鞋柜内的温度和湿度。当温度低于用户设置的值时，系统自动启动加热装置，以维持合适的温度。同时，当湿度高于用户设置的值时，系统会触发加热和通风装置，以确保鞋柜内的湿度保持在理想水平。其次，使用MQ-131传感器来监测臭氧浓度。一旦检测到臭氧浓度超过用户设定的最大值，系统会自动进行臭氧消毒，以保持鞋柜内的空气清新和卫生。第三，MQ-135传感器用于检测鞋柜内氨气浓度。如果氨气浓度升高到危险水平，系统将启动紫外线杀菌装置，以确保鞋柜内没有有害微生物存在。此外，通过霍尔传感器检测鞋柜门的状态。当鞋柜门关闭时，系统自动打开消毒灯以进行杀菌操作，而当鞋柜门打开时，消毒灯会关闭，确保用户的安全。光敏电阻用于检测光照值，当鞋柜门打开且光照值低于用户设置的最小值时，系统会自动打开LED照明灯，提供适当的照明。最后，MQ-2传感器用于监测烟雾值。如果检测到烟雾值超过用户设定的最大值，系统将触发蜂鸣器进行警报，以提醒用户可能存在的火灾风险。用户可以通过按键对各项阈值进行设置，以满足不同需求和环境条件。此外，LCD1602显示屏用于实时显示各种传感器测量值，使用户能够监控鞋柜内环境的状态。
综上所述，这个基于STC89C52单片机的智能鞋柜设计将有效地提供杀菌、除臭和防潮功能，以确保鞋柜内的物品保持干燥、清洁和卫生。这一设计在提高生活质量和环境健康方面具有潜在的重要应用前景。

Abstract
In today’s society, there is a growing concern among people for the health and comfort of their living environments. Specifically, shoe cabinets, as common household items, often face issues such as dampness, mold growth, and unpleasant odors. These problems can adversely affect the quality of the indoor environment and even pose health threats to family members. Additionally, harmful gases such as ammonia and smoke can accumulate inside shoe cabinets, presenting certain safety risks.The aim of this study is to design an intelligent shoe cabinet based on the STC89C52 microcontroller to achieve sterilization, deodorization, and moisture control functions. This intelligent shoe cabinet features the following key functions:Firstly, it employs a DHT11 sensor to monitor the temperature and humidity inside the shoe cabinet. When the temperature falls below the user-defined threshold, the system automatically activates the heating mechanism to maintain the appropriate temperature. Simultaneously, if the humidity exceeds the user-defined threshold, the system triggers both the heating and ventilation systems to ensure that the humidity within the shoe cabinet remains at an ideal level.Secondly, an MQ-131 sensor is used to monitor ozone concentration. Once the detected ozone concentration exceeds the user-set maximum value, the system automatically initiates ozone disinfection to ensure fresh and hygienic air inside the shoe cabinet.Thirdly, an MQ-135 sensor is employed to detect ammonia concentration within the shoe cabinet. If the ammonia concentration rises to a hazardous level, the system activates a UV-C sterilization device to eliminate any harmful microorganisms.Furthermore, a Hall sensor is used to detect the status of the shoe cabinet door. When the door is closed, the system automatically turns on the disinfection lamp for sterilization, and when the door is open, the lamp is turned off, ensuring user safety.A photosensitive resistor is utilized to measure ambient light levels. When the shoe cabinet door is open, and the light level falls below the user-defined minimum, the system automatically switches on the LED illumination, providing appropriate lighting.Lastly, an MQ-2 sensor is used to monitor smoke levels. If smoke levels exceed the user-defined maximum value, the system triggers a buzzer alarm to alert users to potential fire hazards. Users have the flexibility to customize threshold values through buttons, catering to different needs and environmental conditions.In addition, an LCD1602 display screen is integrated to provide real-time visual feedback by displaying various sensor measurements. This allows users to monitor the environmental conditions inside the shoe cabinet.
In summary, this intelligent shoe cabinet design based on the STC89C52 microcontroller effectively provides functions for sterilization, deodorization, and moisture control, ensuring that items inside the shoe cabinet remain dry, clean, and hygienic. This design holds promising potential applications in improving the quality of life and environmental health.
