摘要
在气象监测、环境控制及部分工业场景中，大气压的精准监测与及时预警具有重要意义。传统的大气压监测方式多依赖专业气象设备，存在成本高、便携性差、数据获取不及时等问题，难以满足中小场景下的实时监测需求。
基于 STM32F103C8T6 单片机的大气压监测系统，整合了 BMP180 气压监测模块、3 个独立按键、OLED 显示屏、ESP8266 WIFI 通信模块及声光报警装置，实现了大气压和海拔的自动化监测与智能管理。系统核心功能包括：通过 BMP180 模块实时监测当前环境的气压和海拔，当气压大于预设最大值时，触发声光报警；借助 OLED 显示屏实时显示气压、海拔数据及设备工作状态；支持通过 3 个独立按键设置气压阈值；利用 ESP8266 WIFI 模块将监测数据上传至手机端，实现远程查看数据及阈值设置等远程控制功能。
该系统的实现，有效提升了大气压监测的便捷性与实时性，降低了监测成本，能及时对异常气压进行预警，为相关场景的安全保障和环境管理提供了可靠支持，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
In meteorological monitoring, environmental control, and some industrial scenarios, accurate monitoring and timely early warning of atmospheric pressure are of great significance. Traditional atmospheric pressure monitoring methods mostly rely on professional meteorological equipment, which have problems such as high cost, poor portability, and delayed data acquisition, making it difficult to meet the real-time monitoring needs in small and medium-sized scenarios.
The atmospheric pressure monitoring system based on the STM32F103C8T6 microcontroller integrates BMP180 pressure monitoring module, 3 independent buttons, OLED display, ESP8266 WIFI communication module and sound-light alarm device, realizing automatic monitoring and intelligent management of atmospheric pressure and altitude. The core functions of the system include: real-time monitoring of current environmental pressure and altitude through the BMP180 module, triggering sound-light alarm when the pressure is greater than the preset maximum value; real-time display of pressure, altitude data and equipment working status through the OLED display; supporting the setting of pressure thresholds through 3 independent buttons; uploading monitoring data to the mobile phone through the ESP8266 WIFI module to realize remote data viewing and threshold setting and other remote control functions.
The implementation of this system effectively improves the convenience and real-time performance of atmospheric pressure monitoring, reduces the monitoring cost, can timely warn of abnormal pressure, provides reliable support for safety assurance and environmental management in related scenarios, and also provides a reference for the research and development of similar monitoring equipment, with high practical application value.
