Dense Air Quality Sensor Networks

Currently available reference-grade air quality monitoring stations provide accurate data, but the networks are sparse. Vaisala’s dense network technology makes it possible to complement the existing measurements with compact air quality sensors.

Easy to install on lamp poles, streetlights, or other city infrastructure, these sensors make it economically feasible to construct dense supplementary air quality networks of sensors in a smart city.

By combining the dense air quality measurement data with modern modeling tools, public authorities and the private sector can access high-resolution air quality data for forecasting, benefiting cities and ultimately public health. Specifically, significant gains are made in the following areas:

• Health: Clean air routing alerts and avoiding local hotspots of particulate matter and toxic gases drive down the exposure to poor air quality.
• Traffic: Monitoring e.g. PM_2.5 and N0₂  to verify the effectiveness of clean air zones. Re-routing traffic to limit and prevent creation of local traffic hotspots and street dust (PM₁₀). 
• Public awareness: Sharing air quality index, route finder and other services for public.
• Infrastructure: Air filtering and indoor air quality in large residential, office and public complexes can be optimized by taking into account local air quality.
