People spend most of their time inside buildings. Therefore, indoor air quality monitoring contributes to improve health and well-being. Several studies focus on the critical impact of particulate matter on residential air quality. In 2016, particulate matter caused 412 thousand premature deaths in 41 European countries. This paper presents the development of an affordable health information system for enhanced living environments. The authors propose a cost-effective, modular, scalable, and easy installation solution for particulate matter monitoring. The system is connected to ThingSpeak. It can be installed in any type of building. It requires only a power source and a Wi-Fi network with internet access. The main contribution of this paper is to present the detailed architecture and testing results. The particulate matter monitoring system was installed for one week in a domestic kitchen with an open fireplace. The results showed impact of the biomass burning on indoor air quality. The mean values per day ranged from: 10.53 to 50.62 μg/m for PM, 15.35 to 69.37 μg/m for PM, and 20.1 to 90.69 μg/m for PM. The maximum values per hour were registered at 13:00: 72.14 μg/m for PM, 99.70 μg/m for PM, and 132.13 μg/m for PM. Cost-effective sensors do not have the accuracy level of industrial equipment. Therefore, they should not be used for numerical and in-depth accurate characterization of the environment. Nevertheless, continuous particulate matter monitoring provides consistent data series for analysis of indoor air quality evolution.
人们大部分时间都在室内度过。因此，室内空气质量监测有助于改善健康和幸福感。有几项研究关注颗粒物对住宅空气质量的重大影响。2016 年，颗粒物在 41 个欧洲国家造成 41.2 万人过早死亡。本文介绍了一种经济实惠的健康信息系统的开发，以改善居住环境。作者提出了一种具有成本效益、模块化、可扩展且易于安装的颗粒物监测解决方案。该系统连接到 ThingSpeak。它可以安装在任何类型的建筑物中。它只需要一个电源和一个具有互联网访问权限的 Wi-Fi 网络。本文的主要贡献在于展示详细的架构和测试结果。颗粒物监测系统在一个带有开放式壁炉的家庭厨房中安装了一周。结果表明，生物质燃烧对室内空气质量有影响。每天的平均值范围为：PM 为 10.53 至 50.62μg/m，PM 为 15.35 至 69.37μg/m，PM 为 20.1 至 90.69μg/m。每小时的最大值记录在 13:00:PM 为 72.14μg/m，PM 为 99.70μg/m，PM 为 132.13μg/m。具有成本效益的传感器没有工业设备的精度水平。因此，它们不应用于环境的数值和深入准确的特性描述。然而，颗粒物的连续监测为室内空气质量演变的分析提供了一致的数据系列。
