Smart Environment

Pollution is one of the biggest problems that affects people’s quality of life at cities.

Smart Environment

The challenge

How is human health affected by pollution?

  • Chronic obstructive pulmonary diseases (COPD)
  • Pulmonary cancer
  • Coronary heart diseases
  • Stroke
  • Lower respiratory tract infection

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


IoT Solution for Smart Environment

IoT technology allows users to measure the quality of the air by controlling several parameters.

Air pollution means the amount of Sulfur Dioxide (SO2), Nitrogen Dioxide (NO2), and Carbon Monoxide (CO) in the air exceeds the criteria set by the World Health Organization (WHO).

The Air Quality Index measures the quality of air. It shows the amount and types of gases dissolved in the air. The air quality index is composed of 8 pollutants (PM10, PM2.5, NO2, SO2, CO, O3, NH3, and Pb).

There are 6 categories of air in the air quality index. The categories define the quality of the air. They are as follows; good, satisfactory, moderate, poor, very poor and severe.


Pollutants and Health Breakpoints

AQI Category PM10 (24hr) PM2.5 (24hr) NO2 (24hr) O3 (8hr) CO (8hr) SO2 (24hr) NH3 (24hr)
Good (0-50) 0-50 0-30 0-40 0-50 0-1.0 0-40 0-200
Satisfactory (51-100) 51-100 31-60 41-80 51-100 1.1-2.0 41-80 201-400
Moderately polluted (101-200) 101-250 61-90 81-180 101-168 2.1-10 81-380 401-800
Poor (201-300) 251-350 91-120 181-280 169-208 10-17 381-800 801-1200
Very poor ( 301-400) 351-430 121-250 281-400 209-748 17-34 801-1600 1201-1800
Severe (401-500) 430+ 250+ 400+ 748+ 34+ 1600+ 1800+

Applications of IoT technology in the Environment

Where pollution is measured: Cities, farms and factories.

Parameters to measure pollution:


  • The most frequent pollutant in urban areas.
  • It is formed from high-temperature combustion processes (motor vehicles and electric power plants).
  • Legal limit is 40 microgram/m2


  • The number of premature deaths from exposure to particulate matter (PM) worldwide is likely to more than double to 3.6 million by 2050 under the Baseline, mostly in China and India. The absolute number of premature deaths linked to ground-level ozone by 2050 is also likely to be highest in China and India.
  • Solid or liquid particles: dust, ash, metallic, concrete or pollen.
  • PM10 and PM2.5 can penetrate into the respiratory system, provoking cardiovascular, cerebrovascular and respiratory impacts.


  • High levels of ozone are usually found far away from its main source and they are linked with heat and high pressure episodes.
  • It is formed when strong isolation and pollutants (NO2 and VOCs) react.
  • Higher risk of asthma crisis when the values are elevated.

Benefits of IoT technology in the Environment

  • Air quality measurement is mandatory in cities and industries to demonstrate compliance with environmental regulations.
  • Information about air quality provides citizens with better resources to avoid respiratory pathologies and apply risk prevention measures.
  • 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.

Smart Environment Products

Smart Environment is a product designed to detect different parameters and gas pollutants that impact in the air quality.

Smart Environment Products


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

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

Interoperability: any wireless technology including LPWAN communications: important for Smart Cities projects.
