Air quality monitoring and forecasting using satellite and and low-cost sensors deriving data


The project PNOE improves the current capabilities of air quality monitoring and forecasting models as it uses satellite data of the atmospheric composition coupled with dispersion modelling systems to provide air quality forecasts of high temporal and spatial resolution

Air quality data from autonomous low-cost sensors are further improve the simulated dispersion as they provide point measurements that allow the better representation of the microclimate of each area.

The general goal is the creation of a unified platform that will provide reliable, timely and personalized information about the air quality in order to serve the needs of each user.

Smart Collectors

The development of the PNOE IoT Platform was based on Prisma
Electronics’ PrismaSense™ system, which was redesigned to measure the
concentration of 6 atmospheric pollutants: carbon monoxide (CO), nitrogen
dioxide (NO2), ozone (O3), nitric oxide (ΝΟ) and particles with a diameter
2.5μm (PM2.5) and 10μm (PM10).

Τhe data received from the autonomous sensors are collected by a
microcontroller, which after processing sends them wirelessly to a central
server ( ). The module is an ultra-low power, mixed signal microcontroller
with a dual core 32-bit RISC CPU running at 160Mhz to 240Mhz and
incorporating a 512KB RAM memory. Figure 3 depicts the two sides of the
board. The system can be powered by either battery or USB. The battery
can also be charged via USB.

Software Application

An Application Programming Interface (API) was developed on the air quality platform for receiving datasets from the Smart Collectors, storing
them in a database and sending them to a web and mobile application.

The collected information is displayed in near real time and in high spatial
and temporal resolution. Simplified air quality indices are provided to
citizens along with personalized recommendations on how they can protect their health from air pollution. It is expected that the collected data will also enable the identification of air pollution trends that may lead to policy changes and, in longer term, to behavioral change.
