Smart Environment

Pollution is one of the biggest problems affecting people’s quality of life in cities.

Smart Environment

The challenge

In an increasingly contaminated world, being aware of air quality is often problematic. Thanks to IoT technology, key parameters can be monitored and acted upon.

By 2050, outdoor air pollution (particulate matter and ground-level ozone) is predicted to become the leading cause of environment-related deaths worldwide.


Benefits of Smart Environment solutions

What Smart Environment projects look for…



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



  • Cities that monitor their pollution levels can implement better measures to make their air quality healthier for their neighbours and also for tourists, obtaining environmentally friendly destination certifications.



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


    Health problems:

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

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

Applications of IoT technology in the Environment


The European Environment Agency started to encourage Cities to monitor the Air Quality Index and then inform citizens about air quality, measuring NO2, NO, CO, O3, SO2, PM2.5 and PM10.


Real-time monitoring of emissions on farms by measuring CH4 (methane) and NH3 (ammonia) levels.


Industries and factories (along with households) are one of the main sources of PM (particulate matter emissions).


Controling air quality in villages to attract and promote sustainable tourism, while reducing the impact on the environment.

Fight climate change

Monitor global warming by measuring temperature and CO2 concentration levels.

Smart Environment Products



  • Any wireless technology including LPWAN communications.
  • Any cloud platform: compatibility with city council platforms.

High accuracy sensors from specialized manufacturers are integrated to offer the greatest efficiency.

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 requiring accurate readings and exact concentrations.

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

Solar powered, long battery life.

Physical features:

  • Minimal maintenance costs.
  • Weatherproof enclosure.
  • Easy to deploy.
