Sensitive, low power NO2 sensors developed for air quality monitoring

The research organizations Imec and Holst Centre have developed a small NO₂ sensor featuring a detection limit of

Air quality is typically measured on just a few distinct locations per city, with specialized equipment. Many current gas sensors are large in size, have high power consumption and are too costly to be implemented on a large scale. The new sensor will allow for small, simple, high quality autonomous sensors that can wirelessly communicate via the IoT.

In a next step, proprietary low-cost low-power sensors will be added for CO₂ , VOCs (Volatile Organic Compounds), Ozone, and particle matter. Companies interested in early application validation and development are invited to become a partner in the imec R&D program. IP can also be licensed.
