Air & Noise Monitoring

Smart Cities look for sustainable growth, diminishing the impact of economic and demographic changes and taking advantage of IT and communication technologies.

Air & Noise Monitoring

The challenge

In a society that is becoming increasingly digitalized, citizens are demanding greater transparency from their governments and better management of public resources.

Half of humanity 3.5 billion people live in cities today and 5 billion people are projected to live in cities by 2030.


Benefits of Smart Cities solutions

What Smart Cities projects look for…



  • Public service management and urban problem solving
  • Cities that monitor air or noise pollution levels can implement better measures to make the quality of life healthier for locals and also for tourists, obtaining environmentally friendly destination certifications.



  • Environmental monitoring is useful to explain to citizens the reasons for applying traffic restrictions in case of high pollution.


    Health problems:

  • Information about air quality provides citizens with better resources to avoid respiratory pathologies and apply risk prevention measures.



  • Efficient waste management or being in compliance with environmental legislations lead cities to reduce costs



  • Air quality measurement is mandatory in cities and industries to demonstrate compliance with environmental and sustainable regulations.

Sound interesting… And which are the main applications of this technology?

Applications of IoT technology for Smart Cities

Air quality pollution

Measurement of air pollution levels in urban and industrial spaces.

Acoustic and noise level monitoring

Monitoring of noise levels in urban and industrial spaces.

Smart Parking and Traffic Congestion

Monitoring parking spaces availability in the city. Surveilling vehicles and pedestrian levels to optimize driving and walking routes.

Waste management

Control the filling level of public or industrial waste containers to optimize collection services and transport routes.

Water resources management

Maintenance management and public water consumption savings in parks, green areas, etc.


Detection of people and vehicles in public spaces. Mobility patterns and prediction of mass movements at public events.

Smart Cities Products

Smart Cities are solutions designed to detect different basic parameters related to ambient conditions, noise levels, air quality and luminosity for several applications.

Smart Cities Products

Hardware Features

Products are constantly updated, improved and developed to offer the greatest efficiency

Allied with specialized companies, integrating the best sensors in the market

Any cloud platform: compatibility with city council platforms

High accuracy sensors (continuously improving). Calibrated gases sensors are useful to measure the exact value in PPM’s of a gas concentration, it is designed to be used in applications that require accurate readings and exact concentrations

Particle Matter Sensor -commonly known as “Dust Sensor”- is integrated in the platform. This sensor allows to measure PM1, PM2.5, and PM10 particles. This sensor comes also calibrated from the factory

Noise level and meteorological parameters measurement

Predictive and preventive models can be built

Physical characteristics:

  • Minimal maintenance costs
  • Weatherproof enclosure
  • Easy to deploy

Model and sensors

Air Quality Station

The new Air Quality Station allows the monitorization of the AQI to control pollution at cities and industries.

Main features:

• Measurement of the main air quality parameters: PM, CO, NO2, NO, O3, SO2
• Maximum accuracy thanks to cutting-edge hardware and machine learning algorithm
• Noise level and meteorological parameters measurement
• Removable sensor cartridge for quick sensor exchange
• Communication via 4G
• Real-time data visualization through Libelium Cloud
• Robust, handy, and user-friendly
