摘要
在机房运维中，对环境参数的实时监测、异常预警及便捷管控，对于保障设备稳定运行与数据安全具有关键意义。传统的机房环境管理多依赖人工巡检，存在参数监测不及时、异常预警滞后、远程管理困难等问题，难以满足现代化机房智能化运维的需求。
基于 STM32F103C8T6 单片机的机房环境监测系统（项目编号：mcuclub-dz-1028），整合了 DHT11 温湿度传感器、雨量检测模块、MQ-2 烟雾传感器、霍尔传感器 KY-003、人体热释电 D203S、按键、OLED 显示屏、WiFi 模块 ESP8266 及声光报警装置，实现了对机房环境的自动化监测、报警及远程控制。系统核心功能包括：通过 DHT11 检测温湿度，当温湿度超出设置的上下限值时，进行声光报警；通过雨量检测模块检测是否有水，若检测到水则触发声光报警；通过 MQ-2 烟雾传感器检测火灾，发生火灾时进行声光报警；通过霍尔传感器 KY-003 检测门的开关状态，布防时若检测到人且门被打开，触发声光报警；通过人体热释电 D203S 检测环境是否有人；利用按键可设置各参数阈值、切换布防撤防状态；通过 OLED 显示屏显示各项测量值；通过 WiFi 模块 ESP8266 将检测数据传输到手机端，手机端可设置各阈值并控制布防撤防。
该系统的实现，有效提升了机房环境监测的自动化、智能化水平，通过实时监测、精准报警及远程控制，为机房的安全稳定运行提供了可靠的技术支持，同时为智能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 computer room operation and maintenance, real-time monitoring of environmental parameters, abnormal early warning, and convenient management and control are of crucial significance for ensuring stable operation of equipment and data security. Traditional computer room environment management mostly relies on manual inspections, which has problems such as untimely parameter monitoring, delayed abnormal warning, and difficult remote management, making it difficult to meet the needs of intelligent operation and maintenance of modern computer rooms.
The computer room environment monitoring system based on STM32F103C8T6 microcontroller (Project No.: mcuclub-dz-1028) integrates DHT11 temperature and humidity sensor, rain detection module, MQ-2 smoke sensor, Hall sensor KY-003, human body pyroelectric D203S, buttons, OLED display, WiFi module ESP8266 and sound and light alarm device, realizing automatic monitoring, alarm and remote control of the computer room environment. The core functions of the system include: detecting temperature and humidity through DHT11, and giving an audible and visual alarm when the temperature and humidity exceed the set upper and lower limits; detecting whether there is water through the rain detection module, and triggering an audible and visual alarm if water is detected; detecting fire through the MQ-2 smoke sensor, and giving an audible and visual alarm in case of fire; detecting the door switch state through the Hall sensor KY-003, and triggering an audible and visual alarm if a person is detected and the door is opened during arming; detecting whether there is a person in the environment through the human body pyroelectric D203S; using buttons to set various parameter thresholds and switch between arming and disarming states; displaying various measured values through the OLED display; transmitting the detected data to the mobile phone through the WiFi module ESP8266, and the mobile phone can set various thresholds and control arming and disarming.
The implementation of this system has effectively improved the automation and intelligence level of computer room environment monitoring. Through real-time monitoring, accurate alarm and remote control, it provides reliable technical support for the safe and stable operation of the computer room. At the same time, it provides a reference for the development of the intelligent environment monitoring field, and has high practical value and promotion significance.
