Significant portions of European cities’ population are still exposed to levels of air pollution deemed harmful by the World Health Organization. Given the high impact of air pollution both on human health and the economy, numerous low-cost electrochemical sensor monitoring systems are being installed. The market is forced to develop new air quality monitoring systems to meet the needs of providing forecasting services based on advanced technologies and protocols that utilize certain characteristics such as high accuracy, real-time monitoring, daily and yearly statistics, data access from both experts and simple users with the use of low-cost equipment. In this study, conducted in Athens, Greece, a comparison is attempted between the findings from a low-cost electrochemical sensor device and those of a static, fixed site measurement monitoring station; this comparison is based on the data quality and Air Quality Index (AQI) concerning data accuracy and quality on adverse health effects due to air pollution. With regard to the prediction of different AQI intervals, TPR ranges from 35.2% up to 100.0%, FPR from 0.0% up to 36.1% and FNR from 0.0% up to 38.1%. The outcome of this study reveals flexible and affordable alternatives adopted during the evaluation and calibration of low-cost gas sensors for monitoring.

用于城市环境中空气污染测量的以太低成本传感器装置的性能。应用空气质量指数 (AQI) 的准确性评估

欧洲城市人口的很大一部分仍然暴露于世界卫生组织认为有害的空气污染水平。鉴于空气污染对人类健康和经济的严重影响，许多低成本的电化学传感器监测系统正在安装中。市场被迫开发新的空气质量监测系统，以满足基于先进技术和协议提供预测服务的需求，这些技术和协议利用了某些特性，例如高精度、实时监测、每日和每年的统计数据、专家和专家的数据访问。简单的用户使用低成本设备。在这项在希腊雅典进行的研究中，尝试将低成本电化学传感器设备的发现与静态、固定现场测量监测站；该比较基于数据质量和空气质量指数 (AQI)，涉及空气污染对健康不利影响的数据准确性和质量。对于不同AQI区间的预测，TPR范围从35.2%到100.0%，FPR从0.0%到36.1%，FNR从0.0%到38.1%。这项研究的结果揭示了在评估和校准用于监测的低成本气体传感器期间采用的灵活且负担得起的替代方案。
