摘要
随着人们生活品质的提升和对居家安全与舒适需求的增长，浴室作为家庭环境中的特殊空间，其环境监控与智能控制的重要性日益凸显。传统浴室缺乏有效的环境监测和智能调节手段，存在温度不适、湿度偏高、CO 浓度超标等安全隐患，且控制方式单一，难以满足便捷化、智能化的生活需求。
基于 STM32F103C8T6 单片机的智能浴室远程监控与语音交互系统，整合了温湿度传感器、CO 浓度传感器、D203S 人体热释电模块、继电器、音乐播放器、Wi-Fi 模块、语音识别模块、OLED 显示屏及按键等硬件，实现了多项核心功能：通过温湿度传感器检测浴室环境参数，控制浴霸开关（温度达最大值时自动关闭）和除湿通风设备（湿度低于最小值时停止除湿）；利用 CO 浓度传感器监测有害气体，超标时启动通风并报警；借助人体热释电模块和光照检测，在有人且光照不足时自动开灯；OLED 显示屏实时显示温度、湿度和 CO 浓度；支持手动、语音及手机端（通过 Wi-Fi）控制照明灯、音乐、浴霸和除湿功能。
该系统的实现，有效提升了浴室环境的安全性与舒适度，丰富了控制方式，减少了人工操作，为居家生活提供了便捷、智能的解决方案，同时也为智能家居设备的研发提供了有益参考，具有较强的实际应用价值。

ABSTRACT
With the rapid development of the fresh food industry and the increasing market demand for fruit grading, efficient and accurate fruit sorting has become a key link in improving production efficiency and product quality. The traditional manual sorting method is not only inefficient and labor-intensive, but also prone to inconsistent sorting standards due to human factors, making it difficult to meet the needs of large-scale production.
The fruit sorting system based on STM32F103C8T6 single-chip microcomputer integrates hardware such as weighing modules, servos, motor driver chips, buttons and OLED displays, and realizes several core functions: measuring the weight of fruits through the weighing module, and grading according to two set intervals (less than 1 kg and more than or equal to 1 kg); when the weight is less than 1 kg, start one servo to move left to push the fruit to the left conveyor belt; when the weight is more than or equal to 1 kg, start another servo to move right to push the fruit to the right conveyor belt; drive two DC motors to simulate the operation of the conveyor belt with the help of motor driver chips to realize the transportation of fruits; the fruit weight intervals can be flexibly set through buttons; the OLED display screen shows the weight of the current fruit and the weight intervals of different grades of fruits in real time.
The realization of this system effectively improves the automation and accuracy of fruit sorting, reduces manual intervention, ensures the consistency of sorting standards, provides an efficient and reliable solution for the fruit production and processing link, and also provides a useful reference for the research and development of similar agricultural product sorting equipment, which has certain practical application value.
