摘要
在日常生活与生产中，水质状况对人们的健康及生产活动有着重要影响，传统的水质监测依赖人工采样和实验室分析，存在监测不及时、数据滞后、无法实时调控等问题，难以满足现代对水质精准、高效监测的需求。
基于 STM32F103C8T6 单片机的水质监测系统，整合了水位监测模块、PH 监测模块、防水式 DS18B20、浑浊度监测模块、按键、显示屏及 Wi-Fi 模块，实现了水质的实时监测、自动调控及云端管理。系统核心功能包括：通过水位监测模块实时监测当前水位；借助 PH 监测模块获取水体 PH 值；利用防水式 DS18B20 检测环境水温；通过浑浊度监测模块监测水体浑浊度，当浑浊度大于最大值时自动进行换水，同时触发声光报警；通过按键可设置各项监测指标的阈值；显示屏实时显示测试结果；数据云端同步方面，通过 Wi-Fi 模块将检测数据上传至云端，还可在云端设置阈值、控制换水。
该系统的实现，有效提升了水质监测的自动化、智能化水平，通过实时监测、自动调控、多方式设置及云端管理，为水质监测提供了便捷、高效的解决方案，同时为环境监测领域的发展提供了参考，具有较高的实用价值与推广意义。

ABSTRACT
In daily life and production, water quality has a significant impact on people’s health and production activities. Traditional water quality monitoring relies on manual sampling and laboratory analysis, which has problems such as untimely monitoring, delayed data, and inability to achieve real-time regulation. It is difficult to meet the needs of modern accurate and efficient water quality monitoring.
The water quality monitoring system based on the STM32F103C8T6 single-chip microcomputer integrates a water level monitoring module, a PH monitoring module, a waterproof DS18B20, a turbidity monitoring module, buttons, a display screen, and a Wi-Fi module, realizing real-time monitoring, automatic regulation, and cloud management of water quality. The core functions of the system include: real-time monitoring of the current water level through the water level monitoring module; obtaining the PH value of the water body by means of the PH monitoring module; detecting the ambient water temperature with the waterproof DS18B20; monitoring the turbidity of the water body through the turbidity monitoring module, and when the turbidity exceeds the maximum value, it automatically changes the water and triggers an acousto-optic alarm at the same time; setting the thresholds of various monitoring indicators through buttons; the display screen shows the test results in real time; in terms of data cloud synchronization, the detection data is uploaded to the cloud through the Wi-Fi module, and the thresholds can also be set and water change can be controlled on the cloud.
The realization of this system has effectively improved the automation and intelligence level of water quality monitoring. Through real-time monitoring, automatic regulation, multi-mode setting, and cloud management, it provides a convenient and efficient solution for water quality monitoring. At the same time, it provides a reference for the development of the environmental monitoring field and has high practical value and promotion significance.
