Air Sensor Toolbox: Resources and Funding

Air Sensor ToolboxEPA has provided guidance and other information to make decisions about using air sensors and  conducting a citizen science project to measure air quality

Air Sensor Guidebook

The Air Sensor Guidebook is a comprehensive resource for anyone interested in monitoring local air quality. Topics covered include background on air pollutants and uses for air sensors, what to look for in a sensor, how to collect useful data using sensors, sensor performance guidance, and maintaining your sensing device.

Peer Review and Supporting Literature Review of Air Sensor Technology Performance Targets

To help improve data quality for sensors applied in a nonregulatory fashion, which is growing in prevalence, the United States Environmental Protection Agency (EPA) is considering development of a new voluntary sensor certification program for air sensors. The objective of the report provided here was to evaluate peer-reviewed literature and other sources to identify performance attributes and metrics needed to obtain air monitoring data that are fit for a specific purpose or application. This literature review focused on reports associated with ambient and near-source air monitoring for particulate matter (PM2.5 and PM10), carbon monoxide (CO), nitrogen dioxide (NO2), sulfur dioxide (SO2), and ozone (O3).

Instruction Guide and Macro Analysis Tool for Community-led Air Monitoring

EPA has developed a guide and analysis tool for citizen scientists to evaluate the performance of low-cost air sensors and interpret the data they collect to help learn about local air quality. While EPA developed both of these resources to be suitable for citizen scientists and communities, they are also useful to the broader air sensor user community, both experts and non-experts.

Advice and Frequently Asked Questions (FAQs) for Citizen-Science Environmental Health Assessments

This paper presents two citizen science Environmental Health Assessments and reflects on a decade of collaborations. This work culminated in three lessons learned and a set of Frequently Asked Questions (FAQs), focused on public communication for citizen science projects. This work is not intended as a framework or conceptual approach, a step-by-step method, or a roadmap. It provides advice to translate research into action, and help manage expectations, facilitate understanding, and target resources.
