How do you reliably measure something so ephemeral as the air around us? With a dense network of low-cost sensors – powered by calibration algorithms and analytics that ensure a complete and correct picture.
Air quality varies wildly according to location or time of day. So you need to be able to take targeted actions instantly, to ensure that everyone breathes healthy air, all the time.
That’s only possible if you can rely on a fine-grained and real-time air quality monitoring system. Unfortunately, current air quality sensors are either too expensive and bulky, or inaccurate.
Imec’s real-time air quality monitoring approach enables you to use off-the-shelf sensor boxes, that are getting cheaper with time in urban environments. It’s enabled by the Internet of things:
Governments are under pressure to reduce harmful emissions such as particle matter, NO2 and ozone. Luckily, in the context of a smart city, they can take targeted actions such as adaptive speed limits and dynamic traffic control.
But to take and evaluate targeted actions, you need highly localized air quality data, which the current reference stations can’t provide.
Within the imec City of Things program, we’re testing a large-scale solution that combines data from a wide array of sources:
After automatic calibration and interpolation, this data can be used to make deep analyses and draw a fine-grained real-time air quality map that acts as a digital twin to support smart city policies.
Want to join forces with us to scale up this solution?
Poor indoor air quality is a threat to our health, comfort and productivity. Rising CO2 levels, for example, immediately reduce our ability to focus.
Imec’s technology portfolio allows you to develop an indoor air quality monitoring system based on low-cost sensors. Moreover, we have developed algorithms that make accurate fifteen-minute predictions of the air quality in a room.
This combination of sensors and prediction algorithms allows you to develop closed-loop systems for automatic comfort control.
Air quality is also a growing concern for farmers. They need to comply with regulations that limit emissions of harmful gases such as ammonia and NOx.
By deploying low-cost, low-power air quality sensors in their fields – which could be powered by miniature solar panels – they can get real-time insights into the impact of their activities.
Are you developing a system for real-time air quality monitoring? There are several ways in which imec can assist you speeding up your innovation.
