The Mavericks of Air Quality Monitoring?

From our beginnings helping a school in Northern Thailand monitor the air during the so called ‘Burning Season’ to our strong beliefs in Open Hardware and Open Data. AirGradient is a company that does things differently.

Our Story

AirGradient started as a volunteer project to help a school in Northern Thailand monitor the air quality in classrooms during the highly polluted “burning season”. From the start, we worked with students and educators to not only increase awareness in the area of air quality by building monitors but also in understanding the health impacts of air pollution, and the positive changes that can be made to reducing air pollution.

So from the beginning we put a strong focus on open designs, robust and long-lasting hardware and a strong desire to support people from all around the world with affordable and effective air quality solutions. We believe companies like ours need to act responsible and work towards a healthier and more sustainable environment. As a result joined the 1% for the Planet movement where we pledge to donate 1% of our sales to organizations protecting our planet.

AirGradient is currently the only global air quality monitoring company that makes all its hardware design available for free under a Creative Commons CC-BY-SA license. This means that all electronic schematics, firmware code, CAD files are openly available and we allow (and encourage) other organizations to use them. We also openly publish all our research and algorithms so that others can benefit from the extensive research we are doing.

We live in a world on the brink of climate collapse which will lead to more and more hazardous air-pollution through increased wildfires and heat waves. We want to enable -especially disadvantaged countries and communities- to get access to reliable air quality information by offering affordable air quality monitors on a large scale. Our community of people operating AirGradient indoor and outdoor monitors already consists of thousands in more than 70 countries. They all share the belief that air quality monitoring should be affordable, open and accessible.

“It’s paradox that countries with the highest air pollution often can’t afford high density air quality monitoring. We work hard to provide open, accurate and affordable monitors so that people can protect themselves against harmful pollution.”

Feedback From Our Community

AirGradient have consistently gone above and beyond their contractual duties in order to better support the SAMHE Project.

The San Joaquin Valley of California has extreme climate injustice and the worst air quality in the United States, yet continues poorly monitored. The SEEN Team has partnered with AirGradient to facilitate low-cost monitoring in rural disadvantaged communities, and to increase awareness and education related to air quality. We intend to provide more and better real-time air quality information for local decision makers to act in the best interest of their underserved communities.

Having tested numerous air quality sensors for the projects we are doing I found myself extremely impressed with AirGradient. Not only are they technically first class with their product, they have a level of engagement and adaptability which makes working with them very easy. A welcome element to this is their clear commitment to the importance of environmental issues, showing itself in their interest in the details of our projects - all this helps them to deliver…!

AirGradient has helped us to gain valuable insights into the air quality in each of our classrooms. AirGradient’s dedication to this mission has made it possible for any school or center to monitor their air quality in a cost effective way.

Having used the AirGradient indoor DIY kits as well as the commercial AirGradient ONE in awareness projects with schools and universities here in Thailand, I am very keen on piloting this new outdoor monitor. I am also interested in exchanging ideas and resources for student engagement with this open source projct.

My son has asthma. And I am trying to pass on my love of DYI electronics to him. So I thought we’d build it together to help him track if conditions might be of concern to his health. I’m not sure if Luxembourg’s air is bad, but I wouldn’t call Central Europe exactly good. And with our own sensor we can also track traffic influences etc.
