Pollution is one of the biggest problems that affects people’s quality of life at cities.
How is human health affected by pollution?
Most sources of outdoor air pollution demands concerted action by local, national and regional level policy-makers working in sectors like transport, energy, waste management, urban planning, and agriculture.
By 2050, outdoor air pollution (particulate matter and ground-level ozone) is projected to become the top cause of environmentally related deaths worldwide.
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.
The WHO Air quality guidelines offer global guidance on thresholds and limits for key air pollutants that pose health risks. As an example, the Guidelines indicate that by reducing particulate matter (PM10) pollution from 70 to 20 micrograms per cubic meter (μg/m), we can cut air pollution-related deaths by around 15%.

PARTICLES
Smart Environment is a product designed to detect different parameters and gas pollutants that impact in the air quality.
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.
Physical characteristics:
Air Quality Station
The new Air Quality Station allows the monitorization of the AQI to control pollution at cities and industries.
Main features:
Smart Environment PRO
Smart Environment PRO | Plug&Sense! enables the Air Quality Index (AQI) calculation, thanks to electro-chemical gas sensors providing extremely accurate ppm values and a high-end Particle Matter sensor.
Sensors available:
Wireless communication protocols available to connect devices
ENE.HUB's SMART.NODE grants security, connectivity, environmental control and even Electric Vehicle Charging station to Cal State Fullerton with a streetlight pole that integrates Libelium IoT solutions.
Libelium develops a solution to smart manage waste collection routes to digitize an essential service in cities and towns, that its management is still very traditional.
The construction of the Bilbao Metropolitan South Bypass in a natural environment, close to residential areas requires the measurement of Libelium sensors for precise control of the polluting agents of the development.
