Environmental pollution is a serious problem for cities, and administrations are beginning to take measures to combat it.

This is not a sustainable or viable solution to improve air quality in cities that base decision making on real data.

Measuring air quality today is done via high cost fixed stations, using sensors that require individual laboratory calibration. These static stations limit geographical coverage and involve high installation costs, maintenance and recalibration.

What is SMAQ?

SMAQ is an innovative system for monitoring air quality in urban settings, created with the aim of improving air quality in cities.

How does SMAQ work?


The SMAQ system consists of a monitoring network, in which fixed and lowcost mobile devices combine to maximize coverage along with high-precision sensors to maximize data quality.


The large amount of data collected and processed every few seconds through the expansive network of stations makes it possible to obtain in real time precise details regarding the state of the city.


As a second verification, the system is complemented by a mobile laboratory as a service (LAAS), which monitors the status of low-cost sensors, covers reduncies and conducts indepth studies on specific areas.


This allows administrators to make concrete decisions, as much in the short term as in long-term future planning. Citizens can also access information, such as air quality data, through the mobile application or website, allowing them to choose healthy parks and play areas, hiking trails and bike paths.

Fiware Ready out of the box

We are Fiware IoT Ready. This means that we provide access to the air quality aggregated data of any polygon (e.g. neighborhood, district, etc. level) using FIWARE NGSI APIV2 through our Context Broker.

In addition, we offer free access to an alert system that allows you to know the anomalous conditions registered in each polygon. Alarm system powered by Perseo.


Legal Regulation and Quality of the Data


According to the Directive 2008/50/EC, Cities and Municipalities are obliged to designate zones and agglomerations throughout their territory where assessment (levels measurement, calculation, prediction or estimation)  and management of ambient air quality activities must be carried out, resulting in the drafting of an Air Quality Plan.


Urban Clouds’ SMAQ Technology is internationally certified by the National Accreditation Body (ENAC) and is recognized as a complementary/supplementary method in accordance with Directive 2008/50/EC and local level  United Kingdom: The Air Quality Standards Regulations 2010 – Environmental Protection, Spain: Royal Decree 102/2011, etc.

“Big Data has the power to ease the way we structure our society, businesses and personal lives in the present and for future generations”

The SMAQ system: short and long term savings

The total cost for a year of the SMAQ system over a 50 km2 area is less than that of one conventional fixed station.

100 units connected to a server, of which 70 are mobile and 30 fixed.

An accredited and certified mobile laboratory 1600 hours / year.

Global control panel with publication permissions for data, reporting and alarms.

Citizens’ mobile application: Parks, playgrounds, bike lanes and smart routes.

Access to realtime and historical data through API: Open data, JSON, CSV or customized to your system.

Direct cost savings, up to 60% on current costs.

Coverage measurement is unique. Analyzes every street in detail.

The system is complemented by a mobile laboratory service.

SMAQ is a very competitive system in terms of cost, applications and utility.

SMAQ – Air Quality Outdoor

The system can be integrated into cars, bicycles, etc. Grupo Correos offers this system to its fleet of postmen, currently available only in Spain.

The final product is very versatile and requires no new infrastructure, but instead takes advantage of existing infrastructure, making it possible to adapt the system to any urban core regardless of size, adjusting costs to actual needs. The main segment of this product is local and regional authorities aiming to monitor air quality in a Smart City environment.

“We were impressed about the level of innovation and the non-intrusive mobile sensor technology adapted to our Carts (Postal), acquiring air quality data during daily postal rounds providing flexibility and accuracy. The technology used in Curmos project can be adapted for new sensors and used in different environments.”
