摘　　要：细颗粒物(PM2.5)是地球大气成分中含量很少的组成部分,但它对空气质量和能见度等有重要的影响。病房是患者长期活动的重要场所,要求保持清洁和通风,对于空气质量的要求很高;所以,对病房进行PM2.5监测,是一项很有必要的工作,对于患者健康是很有帮助的。我们研发了一款病房PM2.5监测系统,该系统以C8051F040单片机为控制核心,配以DSM501A粉尘传感器,实时采集数据,最终通过LCD显示模块显示当前环境的PM2.5浓度值。本监测系统具有操作简便,灵敏度高,成本低等优点,为进一步实现病房PM2.5监测仪的市场化和商品化奠定了基础。Particulate matter （PM2. 5） is a group of small amounts of earthg atmosphere components, but it has an important in- fluence on air quality and visibility. The ward is an important place for patients with long - term activities, requirements of clean and ventilated, and the air quality is also very important; therefore, the monitoring for PM2. 5 is a necessary work, is helpful for the health of patients. We developed a PM2. 5 monitoring system for ward, this system uses the C8051F040 microcontroller as the control core, with DSMS01A dust sensor for real -time data acquisition, and finally displays the concentration values of PM2. 5 in current environ- ment through the LCD. The monitoring system has the advantages of simple operation, high sensitivity, low cost advantages, it lays the foundation for commercialization and further market - oriented of PM2. 5 monitor for ward.
