摘要
随着工业生产与日常生活对水资源管理要求的提高，水位的精准监测与智能调控对保障用水安全、避免资源浪费具有重要意义。传统的水位控制方式依赖人工巡检和手动操作，存在响应滞后、监测不及时等问题，难以满足自动化、智能化的管理需求。
基于 STM32F103C8T6 单片机的水位检测报警装置，整合了液位传感器、按键、OLED 显示屏、ESP8266 WiFi 模块、继电器及声光报警装置等，实现了水位的自动化监测与智能控制。系统核心功能包括：通过液位传感器实时检测水位高度，当水位低于设定最小值时自动启动加水设备，达到最大值时停止加水；水位超出最大或低于最小值范围时触发声光报警；支持通过按键设置液位阈值、手动控制加水；利用 OLED 显示屏实时显示水位数据及异常状态；通过 WiFi 模块将监测数据传输至手机端，实现远程监测与加水设备控制。
该系统的实现，有效提升了水位管理的自动化与智能化水平，减少了人工干预，确保了水位的稳定控制，为工业循环水、生活水箱等场景的水资源管理提供了高效、可靠的解决方案，同时为同类监测设备的研发提供了参考，具有较高的实际应用价值。

ABSTRACT
With the increasing requirements for water resource management in industrial production and daily life, accurate monitoring and intelligent regulation of water levels are of great significance for ensuring water safety and avoiding resource waste. Traditional water level control methods rely on manual inspection and manual operation, which have problems such as delayed response and untimely monitoring, making it difficult to meet the needs of automated and intelligent management.
The water level detection and alarm device based on the STM32F103C8T6 microcontroller integrates a liquid level sensor, buttons, an OLED display, an ESP8266 WiFi module, a relay, and an acousto-optic alarm device, realizing automatic monitoring and intelligent control of water levels. The core functions of the system include: real-time detection of water level through a liquid level sensor, automatically starting water supply equipment when the water level is lower than the set minimum value, and stopping when it reaches the maximum value; triggering an acousto-optic alarm when the water level exceeds the maximum or is lower than the minimum range; supporting setting of liquid level thresholds and manual control of water supply through buttons; real-time display of water level data and abnormal status through the OLED display; transmitting monitoring data to the mobile phone via the WiFi module to achieve remote monitoring and control of water supply equipment.
The implementation of this system effectively improves the automation and intelligence level of water level management, reduces manual intervention, ensures stable control of water levels, provides an efficient and reliable solution for water resource management in scenarios such as industrial circulating water and domestic water tanks, and also offers a reference for the research and development of similar monitoring equipment, with high practical application value.
