Data Handling and Analysis

Develop a greater understanding of real-world air quality with low-cost sensor projects such as fenceline monitoring, hot spot analyses, and environmental justice projects.

Data Validation and Analysis

Gain greater confidence in your low-cost sensor data by benchmarking them against regulatory-grade measurements.

Advanced Tools

Gain access to advanced correction algorithms and modern tools designed to handle the large data sets produced by low-cost sensors.

Take Control of Your Air Quality Data

Manage, quality-control, and visualize your data with customized data management and analysis systems developed by air quality monitoring experts.

Data Security

Our low-cost sensor data platform meets the same rigorous federal security standards we follow for projects for the U.S. State Department.

Compare Data Sets

Gain insights by comparing your low-cost sensor data against other data sets, such as current and historical ambient air quality data, wildfire smoke data, meteorological data, and more.


Display actionable, real-time air quality information on your website, or reach the public on any device with automated, real-time alerts.


Measure pollutants of concern using the latest air quality monitoring technology and data systems, with support from our experienced field technicians and scientists.

Select the Right Sensors

Evaluate sensor system performance through laboratory and field studies to properly understand sensor usefulness for air quality monitoring.

Develop and Implement Sensor Siting Plans

Optimize your sensor networks to collect useful data, enhance performance, lower costs, and efficiently manage your sites.


Build institutional and public knowledge of sensor systems and air quality through our customized training events.

Best Practices

Understand low-cost sensors and deployment best practices through customized training courses that fit your needs and knowledge levels.

Community Outreach

Engage the community, achieve your air quality measurement goals, and share your findings with tailored outreach services and public outreach websites and mobile apps.

Youth Education

Kids Making Sense® is an exciting environmental education program that teaches students about air quality and how to measure air pollution using hand-held sensors and mobile phones, empowering them to drive for positive change in their communities. Visit kidsmakingsense.org.

Empowering Youth

Students participate in hands-on science tasks, discuss their findings with an air quality scientist, and share their data with the global air quality community.

They can even use their data to identify local sources of air pollution and take actions to be part of the solution.

Well-Crafted Curriculum

Developed by air quality scientists and educators, and thoroughly tested with teachers and students around the world, Kids Making Sense unites STEM (Science, Technology, Engineering, and Math) education and NGSS (Next Generation Science Standards) with an air sensing system.

Grow Local Awareness and Support

Educate youth about air pollution at a time when they are forming their driving and consumption behaviors.

Increase awareness of your air quality mission among residents who follow science, education, environmental, and public health news. We have conducted Kids Making Sense events across the country, including in schools located in Environmental Justice communities.
