Dangers associated with poor air quality are driving deployments of air quality monitoring technology. These deployments rely on either professional-grade measurement stations or a small number of low-cost sensors integrated into urban infrastructure. In this article, we present a research vision of real-time massive scale air quality sensing that integrates tens of thousands or even millions of air quality sensors to monitor air quality at fine spatial and temporal resolution. We highlight opportunities and challenges of our vision by discussing use cases, key requirements, and reference technologies in order to establish a roadmap on how to realize this vision. We address the feasibility of our vision, introducing a testbed deployment in Helsinki, Finland, and carrying out controlled experiments that address collaborative and opportunistic sensor calibration, a key research challenge for our vision.

迈向大规模空气质量监测

与空气质量差相关的危险正在推动空气质量监测技术的部署。这些部署依赖于专业级测量站或集成到城市基础设施中的少量低成本传感器。在本文中，我们提出了实时大规模空气质量传感的研究愿景，该传感集成了数万甚至数百万个空气质量传感器，以精细的时空分辨率监测空气质量。我们通过讨论用例、关键要求和参考技术来强调我们愿景的机遇和挑战，以建立关于如何实现这一愿景的路线图。我们解决了我们愿景的可行性，在芬兰赫尔辛基引入了测试平台部署，
