Tutorial: Guidelines for implementing low-cost sensor networks for aerosol monitoring

Over the past decade, there has been exponential growth in low-cost air pollution sensing technology. While low-cost sensors can provide a path towards more accessible air quality measurement, there are several guidelines that should be considered prior to deploying a low-cost sensor network. In this tutorial guide, we focus on low-cost aerosol sensors (in this case, PM2.5). The tutorial reviews key guidelines for implementing a low-cost PM sensor network. This article is also associated with a companion web-tutorial (https://nzimmerman-ubc.github.io/lcs-PM-demo/) on downloading and assessing sample low-cost PM sensor data from the PurpleAir network using the new U.S. EPA Fine Particle Sensor Base Testing Guidelines. While this tutorial does not cover every single consideration a researcher or citizen scientist might undertake, it covers the key areas of evaluation and calibration, siting, data reporting, and post-processing. The aim of the tutorial is to improve outcomes for researchers using low-cost PM sensor networks and develop a broader community of practice.
