摘要
在药房管理中，药品储存环境的稳定性对保障药品质量至关重要。温湿度异常、有害气体（如烟雾、一氧化碳、氢气）超标等情况，可能导致药品变质、疗效降低甚至产生安全隐患。传统的人工巡检方式依赖定时记录，存在数据滞后、响应不及时、劳动强度大等问题，难以满足现代化药房对环境监测的精准化、实时化需求。
基于 STM32F103C8T6 单片机的 ZigBee 药房环境监测系统，采用主从机架构，整合了 DHT11 温湿度传感器、MQ-2 烟雾传感器、MQ-7 一氧化碳传感器、MQ-8 氢气传感器、OLED 显示屏、ZigBee 模块、WiFi 模块、按键及声光报警、风扇等执行设备，实现了药房环境的多参数实时监测与智能调控。系统核心功能包括：从机通过各类传感器采集温湿度、烟雾浓度、CO 浓度、氢气浓度，当检测值超过预设阈值时自动启动风扇，并通过 ZigBee 将数据传输至主机；主机接收从机数据后，通过 OLED 显示屏实时展示各项参数，同时支持按键设置各参数阈值，若检测值超标则触发声光报警；主机通过 WiFi 模块将数据推送至手机端，实现远程查看与参数阈值的远程设置。
该系统的实现，有效提升了药房环境监测的自动化与智能化水平，确保了环境参数的实时监控与异常及时响应，为药品储存安全提供了可靠保障，同时为药房信息化管理提供了数据支持，具有较高的实际应用价值。

ABSTRACT
In pharmacy management, the stability of the drug storage environment is crucial for ensuring drug quality. Abnormal temperature and humidity, excessive harmful gases (such as smoke, carbon monoxide, hydrogen), and other conditions may cause drug deterioration, reduced efficacy, or even safety hazards. Traditional manual inspection methods rely on timed records, which have problems such as data lag, delayed response, and high labor intensity, making it difficult to meet the needs of modern pharmacies for precise and real-time environmental monitoring.
The ZigBee pharmacy environment monitoring system based on the STM32F103C8T6 microcontroller adopts a master-slave architecture, integrating DHT11 temperature and humidity sensors, MQ-2 smoke sensors, MQ-7 carbon monoxide sensors, MQ-8 hydrogen sensors, OLED displays, ZigBee modules, WiFi modules, buttons, and sound-light alarm, fans and other executive devices, realizing multi-parameter real-time monitoring and intelligent regulation of the pharmacy environment. The core functions of the system include: the slave machine collects temperature and humidity, smoke concentration, CO concentration, and hydrogen concentration through various sensors, automatically starts the fan when the detected value exceeds the preset threshold, and transmits data to the master machine through ZigBee; after receiving the slave machine data, the master machine displays various parameters in real-time through the OLED display, and supports setting each parameter threshold through buttons, and triggers an acousto-optic alarm if the detected value exceeds the standard; the master machine pushes data to the mobile phone through the WiFi module to realize remote viewing and remote setting of parameter thresholds.
The implementation of this system effectively improves the automation and intelligence level of pharmacy environment monitoring, ensures real-time monitoring of environmental parameters and timely response to abnormalities, provides a reliable guarantee for drug storage safety, and also provides data support for pharmacy information management, which has high practical application value.
