AirGradient Go combines practical portability with data quality and openness, so it works for both everyday awareness and deeper analysis.
Track PM2.5, CO2, TVOC, and atmospheric pressure in the same session so you can compare outdoor pollution events with indoor comfort and airflow conditions.
Replay where exposure changed across your day, then connect specific spikes to roads, intersections, enclosed spaces, or ventilation changes.
Record independently while moving. Keep sessions on-device and sync later, which is useful when you do not want continuous phone pairing.
Designed for repeated real-world use on commutes, school runs, field walks, and transit routes, not only desk demos or one-off tests.
Small differences in ventilation, traffic, and distance from roads can change what you are exposed to, often within minutes. A single city-level value is useful context, but it does not fully describe personal exposure over a day.
Outdoors, AirGradient Go helps you track particulate matter exposure from traffic, urban pollution, and wildfire smoke while you move through different micro-environments. Indoors, it helps you track CO2 trends to understand ventilation quality for better focus and comfort in classrooms, offices, and homes, while TVOC and atmospheric pressure provide additional context for changing environmental conditions.
For fixed monitoring at home or buildings, see our indoor monitor and outdoor monitor pages. Together, portable and fixed measurements give a stronger picture of where exposure starts and how it propagates.
AirGradient Go is designed to move through the places that shape daily exposure, from workouts and commutes to everyday indoor environments.
See how ventilation and occupancy affect indoor air during exercise.
Bring monitoring into school runs, walks, cycling, and transit using the included carry bag with air flow openings.
Compare how indoor spaces differ across homes, cafes, offices, and other shared places.
The AirGradient app turns measurements into a clear personal exposure story, so you can understand what happened, where it happened, and what to improve next.
In the app, you can review route overlays, timeline patterns, and repeated exposure behavior across different places and times. You can map route exposure on commutes, walks, and runs, track trends across weeks and months, identify pollution hotspots to avoid repeat exposure, and share recorded routes when needed.
For teams and communities, these repeated measurements can also support clearer discussions about exposure reduction strategies and practical interventions.
We selected sensors based on real-world performance and long-term stability - not what was easiest to shrink. At the same time, AirGradient Go is designed to be easy to use in daily life, with clear on-device feedback and a straightforward app workflow for review.
Building on our experience working alongside research institutions and community-driven monitoring initiatives, including open-seneca, directly informed the design of AirGradient Go.
Particulate Matter: We selected the Sensirion SPS30 after comprehensive testing for strong real-world consistency in portable use. Curious how we tested it (spoiler alert: With an RC car), read here.
CO2: We are currently testing three different CO2 sensors to make sure we pick one that delivers the best results for a portable monitor. This validation process focuses on stability, response behavior, and performance across different environments.
Temperature, Humidity, Pressure: Features an isolated probe, designed to minimize the impact of internal device heat on your readings, so your environmental data remains more representative while moving or stationary.
Examples where portable monitoring adds value beyond fixed-location sensors.
Compare multiple commuting routes and departure times to choose lower-exposure options without relying on guesswork.
Understand how school pickup zones, drop-off traffic, and indoor waiting areas affect short but frequent exposure windows.
Collect route-based evidence during neighborhood walks, project assessments, or baseline surveys to support local decisions.
Validate ventilation improvements by comparing repeated pre/post sessions across meeting rooms, corridors, and break areas.

Short answers to common pre-launch questions.
No. AirGradient Go includes on-device storage and built-in GPS for standalone recording sessions.
No. It is useful both outdoors for PM exposure and indoors for ventilation awareness with CO2 trends, with TVOC and atmospheric pressure adding extra environmental context.
Yes. It can be used for stationary logging when you want to track one location over longer periods.
Yes. AirGradient Go follows the same open philosophy with open hardware and open firmware.

Join the Pre-Launch ListThis 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 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.
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.
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).
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.
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.
