摘要
随着城市化和工业化的迅速发展，水污染问题变得越来越严重，对人类健康和自然环境造成了巨大威胁。现有的水质检测手段通常效率低下、成本昂贵且缺乏实时性，无法适应现代水质管理的要求。因此，构建一个高效、简便、实时的水质监测系统显得极为关键。
本设计基于STM32F103C8T6单片机，结合多种水质传感器，构建了一套功能完善的水质监测系统。该系统通过PH传感器实时监测水环境PH值，PH值超出默认范围（6~8）时会自动触发声光报警。利用TDS检测模块测量水中电解质浓度（0~20000uS/cm），为水质评估提供重要参考。通过水位传感器实时监测水位（0~100%），水位低于30%时自动启动加水功能以保水位在安全范围。浑浊度传感器用于检测水的浑浊度（0~400NTU），浑浊度超100NTU时自动开启净化水泵处理。通过OLED显示屏实时显示PH值、电解质浓度、水位、浑浊度等测量数据，方便用户实时了解水质状况。并通过按键设置各监测参数阈值，手动控制加水、净化水泵及取消声光报警，提高了系统灵活性与实用性。
本方案中的水质监控系统具备显著的应用意义。它实现了对水质多指标的实时监控与自动调节，显著提升了水质检测的效率与精确度。借助于即时预警与自动处理机制，该系统能够迅速应对水质的波动，为水质管理领域提供了坚实的技术支持。

ABSTRACT
With the rapid development of urbanization and industrialization, water pollution has become increasingly serious, posing a huge threat to human health and the natural environment. The existing water quality detection methods are usually inefficient, expensive, and lack real-time performance, which cannot meet the requirements of modern water quality management. Therefore, building an efficient, simple, and real-time water quality monitoring system is extremely crucial.
This design is based on the STM32F103C8T6 microcontroller, combined with various water quality sensors, to construct a fully functional water quality monitoring system. The system monitors the pH value of the water environment in real time through a pH sensor. When the pH value exceeds the default range (6-8), it will automatically trigger an audible and visual alarm. Using TDS detection module to measure electrolyte concentration in water (0-20000uS/cm) provides important reference for water quality assessment. Real time monitoring of water level (0-100%) through a water level sensor, and automatic activation of water addition function when the water level is below 30% to ensure that the water level is within a safe range. The turbidity sensor is used to detect the turbidity of water (0~400NTU), and when the turbidity exceeds 100NTU, the purification water pump will be automatically turned on for treatment. Real time display of pH value, electrolyte concentration, water level, turbidity and other measurement data through OLED display screen, making it convenient for users to understand the water quality status in real time. And by setting the threshold values of various monitoring parameters through buttons, manually controlling the water addition and purification pumps, and canceling the sound and light alarms, the flexibility and practicality of the system have been improved.
The water quality monitoring system in this plan has significant application significance. It realizes real-time monitoring and automatic adjustment of multiple indicators of water quality, significantly improving the efficiency and accuracy of water quality detection. With the help of real-time warning and automatic processing mechanisms, the system can quickly respond to fluctuations in water quality, providing solid technical support for the field of water quality management.
