Pollution is one of the biggest problems that affects people’s quality of life at cities.
The challenge
How is human health affected by pollution?
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+ |

Smart Environment is a product designed to detect different parameters and gas pollutants that impact in the air quality.
Features
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.
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.
Solar powered.
Long battery life.
Predictive and preventive models can be built.
