Outdoor Air Quality
Urbanisation clearly shows that air pollution affects our own health and the environment in densely populated areas. We do not have a solution for that, but we strongly believe that measuring is a good way to scientifically prove what we need to do.
As Earth becomes ever more populated, the destiny of our survival is in our own hands.
Ninety-seven per cent of climate scientists agree that climate-warming trends over the past century are very likely due to human activities. We can testify that our sensors are showing an increasing level of CO₂.
Before the Industrial Revolution, CO₂ levels did not exceed 300 ppm. In 2013, CO₂ levels surpassed 400 ppm for the first time in recorded history. This relentless rise in CO₂ exposes the constant relationship between fossil-fuel burning and CO₂ levels.
Our sensors can't provide fresh air, but we believe that what is measured can be improved.

Today, monitoring outdoor air quality is made with very expensive and bulky technology, which prevents initiatives from individuals or smaller organizations. Our new High-Resolution Platform (HPP) is opening up for new opportunities: we can measure gases with infrared technology with almost the same precision at a fraction of the existing cost (about 5%) and with a much smaller unit.
We also have sensors like the S8 and the K30 that are used to complement high precision instruments (laser) on the ground level and in balloons.
In cities, an expensive instrument might be placed on the rooftop of a skyscraper, but it does not reveal pockets of pollution on ground level, which is something we have found through problems with sensing indoor air quality.
A low-cost outdoor air quality monitor can be used for:
- Personal monitoring
- Information/political-commercial decisions
- Source identification
Make sense of air
Did you know that more than 5.5 million people die due to bad air quality every year?
Good air quality is something that many take for granted, but in many parts of the world, the reality is much crueller than that. People have no choice but to breathe the air they are surrounded by, even if it burns in their throats and causes lung and cardiovascular diseases. This is not only happening in Asia. For example, new reports show that 1,000 people die prematurely in Stockholm County every year due to air pollution. We make sensors that measure carbon dioxide and air quality for people all around the globe in order to make better decisions - for yourself, the environment, and your fellow humans.
Sensors do not provide fresh air, but we believe in the following statement from the book Freakonomics by Levitt: "Knowing what to measure and how to measure it makes a complicated world much less so".
7 million premature deaths annually are linked to air pollution:
WHO releases country estimates on air pollution exposure and health impact. New interactive maps highlight areas within countries that exceed WHO air quality limits:

A WHO air quality model confirms that 92% of the world’s population lives in places where air quality levels exceed WHO limits.
Our K30 sensor is used in the Sensor Networks for Air Quality (SNAQ). The project is equipped with low-cost sensors and has been running since 2011 in several places around Europe (Heathrow Airport, for example).
Drones can be used to measure air quality. Our LPL sensor is up and flying in a research project (Martin Kunz, Max Planck Institute for Biogeochemistry, Germany).
