基于单片机的厨房调料盒环境测控系统
摘要
随着现代智能家居理念不断普及，厨房作为食品调料储存的重要场所，内部温湿度环境直接影响各类调味原料的保存周期与食用安全性。长期高湿环境极易造成调料结块、受潮霉变、滋生微生物，不仅缩短调料存放时长，还会带来食品安全隐患。传统厨房调料储存方式缺少常态化环境监测手段，大多依靠人工定期查看，存在环境变化发现滞后、无自动告警、环境数据无法直观展示等不足，难以实现调料储存环境的持续管控。本文提出一种基于 STM32F103C8T6 单片机的厨房调料盒环境测控系统设计方案。系统集成温湿度采集、本地人机交互、阈值自定义、本地声光报警、OLED 实时数据显示等核心功能。利用 DHT11 传感器实时采集调料盒内部环境温湿度数据，将采集得到的湿度参数与用户预设湿度上限自动比对；当监测湿度超过设定最大值时，设备立即触发本地声光报警，提醒用户及时除湿；系统搭载独立按键，支持湿度上限自定义设置，搭配 OLED 显示屏实时展示实时温湿度测量值与预设湿度上限。本系统有效解决传统调料储存缺少自动监测预警、环境状态可视化程度低等痛点，实现调料储存环境实时监测、湿度超标自动报警、参数本地可视化展示，提升厨房调料储存管理智能化水平，具备良好的家居配套应用价值与推广前景。

With the continuous popularization of modern smart home concepts, the kitchen serves as an important storage place for food condiments, and the internal temperature and humidity environment directly affect the shelf life and edible safety of various seasoning raw materials. Long-term high humidity environment can easily cause condiment caking, damp mildew and microbial growth, which not only shortens the storage time of condiments, but also brings hidden dangers to food safety. The traditional storage method of kitchen condiments lacks normalized environmental monitoring means and mostly relies on regular manual inspection. It has disadvantages such as delayed discovery of environmental changes, absence of automatic alarm and invisible environmental data, making it difficult to continuously control the condiment storage environment. This paper proposes a design scheme of environment measurement and control system for kitchen condiment box based on STM32F103C8T6 microcontroller. The system integrates core functions including temperature and humidity collection, local human-computer interaction, threshold customization, local audible and visual alarm, and real-time data display on OLED. The DHT11 sensor is used to collect real-time temperature and humidity data inside the condiment box, and the collected humidity parameters are automatically compared with the maximum humidity preset by users. When the monitored humidity exceeds the set maximum value, the device immediately triggers local audible and visual alarms to remind users to dehumidify in time. Equipped with independent keys, the system supports custom setting of the maximum humidity value, and an OLED display screen is matched to show the measured real-time temperature and humidity as well as the preset maximum humidity in real time. This system effectively solves the pain points of lacking automatic monitoring and early warning and low visualization of environmental status in traditional condiment storage. It realizes real-time monitoring of condiment storage environment, automatic alarm for excessive humidity and local visual display of parameters. The system improves the intelligent level of kitchen condiment storage management, and has favorable supporting application value and promotion prospects for household use.
