AIRcityQUAL System

The AIRcityQUAL System measures and monitors Air Quality for Smart Cities.


Air Quality, Noise and Meteorological Monitoring System for smart cities (IoT solutions)

The AIRcityQUAL System constitutes a complete and integrated solution for the continuous monitoring of all the parameters of interest that characterize the degree of environmental pollution in the urban environments.

It represents a new paradigm for the pollution monitoring of cities due to the excellent qualities that characterize it.



  • Accuracy in measurements.
  • Quick response with real-time data.
  • Affordable price.
  • Rapid implementation of the automatic measuring stations at any point in the city, mounting them on streetlights, traffic lights, fixed to front of buildings or on bus stop shelters.
  • Maximum representativeness of the measures due to the proximity of the stations to the critical zones due to their high density of traffic and other polluting sources.
  • Possibility of establishing networks with a higher density of measurement points, as an independent monitoring network or as a complement to the existing measurement networks based on complex and expensive gas analyzers.
  • Does not require the construction of booths to protect the sensors, as it is the case of stations based on gas analyzers.
  • Very low maintenance.
  • Data Transmission in real-time through any of the available communication channels or networks: GPRS/3G/4G/5G, LPWAN BB, NB IoT, Ethernet, Satellite, etc.
