Abstract

Personal environmental exposure monitoring is an important method for evaluating detrimental effects of pollutants (or otherwise) on human health. We present an open source, affordable personal environmental exposure monitoring system based on off-the shelf components. The system is meant to be worn around the neck for continuous environmental monitoring, which can be useful for future epidemiological studies as well as personal exposure monitoring. We provide the schematics for the Printed Circuit Board as well as the firmware to run the system under a permissive license. Specifically, the system is designed to count airborne particles (PM0.5, PM1.0, PM2.5, PM4.0, PM10), measure CO, CO2, O3, H2S, as well as temperature, pressure, motion, and the relative presence of Volatile Organic Compounds (VOCs). This low-cost and open-source device presented here is an important step to empower individuals, researchers, and underserved communities alike to better understand how daily life within one’s own environments impacts our health and welfare.

超局部空气区域评估器(雾霾):用于个人环境暴露监测的开源系统

个人环境暴露监测是评价污染物(或其他)对人体健康有害影响的重要方法。我们提出了一种基于现成组件的开源，价格合理的个人环境暴露监测系统。该系统可以戴在脖子上进行持续的环境监测，这对未来的流行病学研究和个人暴露监测都很有用。我们提供印刷电路板的原理图以及在许可许可下运行系统的固件。具体来说，该系统旨在计算空气中的颗粒物(PM0.5, PM1.0, PM2.5, PM4.0, PM10)，测量CO, CO2, O3, H2S，以及温度，压力，运动和挥发性有机化合物(VOCs)的相对存在。这里展示的这种低成本和开源设备是重要的一步，它使个人、研究人员和服务不足的社区都能更好地了解自己环境中的日常生活如何影响我们的健康和福祉。
