在当今社会，水资源的高效利用和水质安全保障成为人们关注的焦点。传统流量计功能单一，仅能测量水流量，难以满足用户对水质监测、用水管理和远程控制的综合需求。因此，开发一种多种功能的数字流量计具有重要的现实意义。
本设计以STM32F103C8T6单片机为控制核心。通过水流量传感器实时监测当前水流量和累积用水量，并在水流量低于设定阈值时，通过手机弹窗和震动提醒用户。通过TDS传感器检测水质，当水质超过设定的最大值时，触发声光报警提醒。通过DS18B20温度传感器实时测量水温。通过按键设置阈值和控制水泵开关，通过OLED显示屏实时显示各项数据。并通过WiFi模块将数据上传至手机端，用户可在手机上远程设置阈值和控制水泵，实现了智能化用水管理。
在实物测试中，该数字流量计运行稳定，各项功能表现良好，满足系统设计需求，能够为用户提供便捷的用水管理和水质安全保障，具有良好的应用前景。
In today’s society, the efficient utilization of water resources and the guarantee of water quality safety have become the focus of people’s attention. Traditional flow meters have a single function and can only measure water flow, making it difficult to meet the comprehensive needs of users for water quality monitoring, water management, and remote control. Therefore, developing a multifunctional digital flowmeter has important practical significance.
This design uses STM32F103C8T6 microcontroller as the control core. Real time monitoring of current water flow and cumulative water consumption through a water flow sensor, and alerting users through mobile phone pop ups and vibrations when the water flow falls below a set threshold. Detecting water quality through TDS sensors, triggering sound and light alarms when the water quality exceeds the set maximum value. Real time measurement of water temperature through DS18B20 temperature sensor. Set threshold and control water pump switch through buttons, and display various data in real time through OLED display screen. And the data is uploaded to the mobile phone through the WiFi module, allowing users to remotely set thresholds and control water pumps on their phones, achieving intelligent water management.
In physical testing, the digital flowmeter runs stably, performs well in various functions, meets the system design requirements, and can provide users with convenient water management and water quality safety assurance, with good application prospects.
