Seven million people die every year due to air pollution. Monitoring air quality enables people worldwide to better protect themselves.
We are on a mission to bring accurate and affordable air quality monitoring to every corner of the planet and we are supported by a community of more than 10,000 engaged citizens who have already deployed an AirGradient monitor.
To maximize our impact, we have completely open-sourced and shared our monitor design so that others can build upon it.
We are blessed to have such an active community. Read more about community engagement.

Join our NewsletterAirGradient monitors are fully open-source, and you can send the data to any server, i.e. Home Assistant or Homey. In case you do not have your own data platform we include access to the AirGradient dashboard - a data platform specifically made for air quality monitoring. Outdoor monitors can also be displayed on the AirGradient Map.
The powerful dashboard and map lets you immediately see the air quality and environmental status of multiple locations. Built for speed and scale.
You can set up specific alerts and are notified automatically if air quality is exceeds your defined ranges.
The air quality data is saved in 5 minute intervals and all data can be easily exported for further analysis.
Get powerful daily and weekly reports detailing the air quality of each location, providing you with a clear, concise summaries at a glance.
This manifesto reflects our core values and the principles we stand for:
We must be bold. We always follow our convictions and call out the issues that matter, sharing our views on topics surrounding air quality and environmental responsibility. We will not compromise for profit. We believe that open, informed, and candid discussions are the catalysts for meaningful change. We will lead by example and become a driving force for environmental monitoring.
We will deliver benefits for both people and the planet. This is why we prioritise creating high-quality air quality monitors with designs that enable easy repairs and recycling, thereby extending the product’s lifespan and reducing its environmental footprint.
Our research is driven by a commitment to environmental protection, not by profits. This is why we don’t patent our air quality monitor designs but on the contrary, share them openly, allowing everyone to build them and to contribute to positive change. We do not lock users into proprietary eco-systems and we encourage sharing of air quality data and algorithms as a public good.
We want to raise awareness about air pollution through active community building with a strong focus on informing about the dangers of air pollution. We actively support environmental justice organisations and educational institutions in their missions to provide healthier environments for everyone.
To deliver positive impacts on the communities, and the environment, we must sustain our business model. However we will not prioritise profits above our convictions. We embed this rationale into our everyday decision-making processes throughout all layers of our company. (e.g. by joining 1% for the Planet).
AirGradient is built on a foundation of openness and inclusivity. We aim to make our products and services available to a wide range of users with a special focus on underrepresented communities. We strive to work with all organisations that want to make a positive contribution independent of their financial means.
100% commitment to accurate and sustainable air quality monitoring.
We are working with leading universities to achieve high levels of accuracy and for our outdoor monitor are currently running co-location testing in four continents.
All components have been selected for maximum lifetime. The monitors are easy to assemble, maintain and repair and we provide spare parts.
We actively support organizations that work towards a healthier air quality by providing open source monitor kits, workshops and donations.
We are known for giving 100% to help our customers reach their goals. Get in touch with us. We love to hear from you and how we can support you in monitoring your air quality!
The monitors are licensed under CC license with complete documentation. Our community maintains integrations to popular platforms like Home Assistant.
We actively support organizations in all parts of the world with affordable monitoring hardware and donations. Contact us to discuss how we can support your organization.
Unlike competitors, the data your monitor delivers belongs to you. Period. We support organizations with proper attribution for the networks they setup.
We design our products to have a low environmental footprint, use paper based packaging material and also request our suppliers to use environmentally-friendly packaging material.
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 beginning, we have worked with students and educators to building hardware to increase awareness in the area of air quality, to understand the health impacts of pollutants, and to empower the positive changes that can be made to reduce air pollution.The experience and expertise that we gained designing and manufacturing our professional AirGradient ONE RESET Air Accredited Monitor has been put into our open-source / open-hardware air quality build instructions and kits.The industry-grade sensor modules used in our open hardware monitors are the same modules found in pre-built monitors costing hundreds of dollars. As a result, you get highly accurate data quality, essential to having a reliable understanding of the air around you.
We are fortunate to have such a strong community sharing our mission to bring open, accurate and affordable air quality monitoring to everyone running thousands of open-hardware monitors in more than 70 countries around the world.

If you like our open hardware monitors please spread the news and consider writing a review about them! Since our monitor designs are open and under Creative Common license, and we want honest and unbiased reviews it is against our ethos to pay for reviews. But we would be very happy to support in other ways.
