传统的空气质量监测依赖于少量高端设备的点测量。最近低成本空气传感技术的发展将彻底改变空气质量数据的收集和利用方式。虽然在低成本监测领域出现了几种技术，但所有技术都面临着数据质量方面的类似挑战。一种显示出特别前景的技术是电解（也称为电流计）传感器。这些传感器响应目标污染物产生电流。这项工作解决了实际模型的发展，了解和量化的电解传感器的信号响应。这种模型补偿了对传感器响应的混淆效应，例如环境温度和湿度，并解决了影响低成本传感器可用性的其他问题，例如传感器漂移和传感器间可变性。
Traditional air quality monitoring relies on point measurements from a small number of high-end devices. The recent growth in low-cost air sensing technology stands to revolutionize the way in which air quality data are collected and utilized. While several technologies have emerged in the field of low-cost monitoring, all suffer from similar challenges in data quality. One technology that shows particular promise is that of electrolytic (also known as amperometric) sensors. These sensors produce an electric current in response to target pollutants. This work addresses the development of practical models for understanding and quantifying the signal response of electrolytic sensors. Such models compensate for confounding effects on the sensor response, such as ambient temperature and humidity, and address other issues that affect the usability of low-cost sensors, such as sensor drift and inter-sensor variability.
