Frequent Questions About Air Sensors

This page provides answers to common questions about the use of air sensor technology to measure air quality conditions.

Air Sensor Collocation Instruction Guide

The collocation instruction guide provides information to air sensor users on how to evaluate their performance and accuracy in measuring air quality that recommends locating the sensors next to regulatory-grade reference monitorings.

Instruction Guide and Macro Analysis Tool: Evaluating Air Sensors by Collocation with Federal Reference Monitors

EPA has created an instruction guide on conducting a successful collocation evaluation of low-cost air sensors and macro analysis tool for analyzing collected data.

Household Energy and Clean Cookstove Research

EPA is an international leader in clean cookstove research and provides independent scientific data on cookstove emissions and energy efficiency to support the development of cleaner sustainable cooking technologies.

Research on Near Roadway and Other Near Source Air Pollution

Research has shown that living and working near sources of air pollution can lead to higher exposures to air contaminants many of which contribute to adverse health effects including reduced lung function, asthma, cardiovascular disease and premature death

Air Quality and Climate Change Research

EPA is conducting research to understand the relationships between climate change and air quality by advancing the understanding of temperature changs on ozone and particulate matter concentrations and changes in pollen and allergic disease patterns.

EPA Order 1000.19: Policy and Procedures for Managing Dual Use Research of Concern

This Order establishes a systematic approach for EPA researchers to identify and mitigate when and how the risks that knowledge, information, products, or technologies produced by certain life sciences research may be misapplied in significant ways.

Air Sensor Toolbox

The toolbox provides information on tthe performance, evaluation and use of air sensor technology to improve accuracy and data interpretation that can benefit citizen scientists, researchers, and developers.
