Cities such as London, Paris, and Perth have worked with Clarity to implement hybrid, low-cost ambient air quality monitoring networks to supplement existing regulatory air pollution measurement networks.
No separate software purchase. No add-on warranties. No unexpected expenses.
With one upfront service, we’re giving you the affordability, flexibility, and autonomy to eliminate all of your air quality blind spots.
Self-powered Clarity Node-S air quality monitoring hardware measures PM2.5 and NO2 and serves as a platform for additional modules that measure Wind, Black Carbon, and Ozone.

There is an increasing demand for high-resolution, accurate air pollution data.
Communities around the world are creating increased public accountability for air quality managers.
Annual federal funding for U.S. state and local air quality management grants has decreased by 20% since 2004 after adjusting for inflation.
Federal reference monitors (FRM) are designed to monitor air quality trends year-over-year — but can’t identify day-to-day, localized pollution events.
Many air quality regulations are decades old and do not adequately address modern-day air pollution challenges.
To support a broader understanding and more effective use of this technology, the US EPA recently released performance standards for air sensors that will help to better characterize the performance of commercially available air sensors in a clear and standardized way.
Read our whitepaperA robust air sensor network can help raise awareness of air quality, protect citizens from air pollution exposure, and mitigate air pollution concerns in your community.
Deploy dozens of low-cost air quality sensors for the equivalent cost of one Federal Reference Monitor.
Collect high resolution, accurate air quality measurements at unmonitored sites.
Share real-time air quality information with your stakeholders to understand short-term changes in air pollution.
Accurate and localized air pollution data will enable you to make strategic data-driven decisions to protect public health.
Clarity’s solution complements regulatory monitoring by filling spatial data gaps with a dense, high-resolution network of calibrated sensors. Our Node-S air quality monitoring devices and Add-On Modules offer measurements of key pollutants like PM₂.₅, NO₂, O₃, and black carbon, enabling agencies to track pollution trends in underserved or high-risk areas. Clarity also supports collocation and calibration with reference monitors to ensure data is reliable for supplemental monitoring applications.
Clarity’s data is ideal for non-regulatory supplemental monitoring (NSIM), community exposure assessments, and environmental justice reporting. While not a direct substitute for FRM/FEM instruments, Clarity’s FEM Ozone Module is EPA-designated, and our Node-S air quality sensor has been accepted for use on the EPA Fire & Smoke Map, demonstrating the reliability of our calibrated sensor data for government use.
Accuracy is maintained through a combination of global and local calibration models, continuous QA/QC, and performance benchmarking. Clarity sensors are regularly collocated with regulatory monitors during deployment to validate performance. We also offer Add-On Services like calibration reviews, accuracy reporting, and data validation to support decision-grade measurements.
Yes. Clarity’s cloud-based platform includes a robust, open API that allows agencies to integrate air quality data into internal dashboards, GIS platforms, or public portals. Many government users have successfully connected Clarity data to ArcGIS, Open Data platforms, and third-party health dashboards.
Absolutely. The plug-and-play nature of Clarity’s sensors—solar-powered, cellular-connected, and modular—makes it easy to scale deployments citywide or regionally. For example, Breathe London deployed 135+ sensors across the city to monitor pollution in neighborhoods, around schools, and near transportation corridors.
Clarity provides comprehensive support through our Project Support Services, including assistance with sensor siting, deployment, data QA/QC, stakeholder reporting, and regulatory engagement. Government partners also have access to onboarding, training, and ongoing technical support from our expert air quality team.
Clarity’s modular platform supports the monitoring of PM₂.₅, PM₁₀, NO₂, O₃, black carbon, and a range of gases via the Multi-Gas Module, including CO and VOCs. This flexibility allows agencies to tailor deployments to local air quality priorities—from traffic emissions to wildfire smoke or industrial pollutants.
Environmental agencies use real-time sensor data from Clarity to trigger public alerts, shape pollution mitigation policies, and prioritize health interventions in high-risk communities. Tools like Air Quality Alarms and OpenMap provide actionable insights that help public health departments and emergency responders protect vulnerable populations during events like wildfires, dust storms, or high-traffic days.
