Portable Fine Particle Measurement

The objective of this project is to measure air quality by measuring the quantity of fine particles.
Thanks to its portability, it will be possible to carry out measurements at home or on the move.
Air quality and fine particles: Particulate matter (PM) is generally defined as fine solid particles carried by the air (source: Wikipedia). Fine particles penetrate deep into the lungs. They can cause inflammation and worsen the health of people with heart and lung disease.
The writing device measures the presence rate of PM10 and PM2.5 particles
The writing device shall measure the presence of PM10 and PM2,5
The term “PM10” refers to particles with a diameter of less than 10 micrometers.
PM2,5” means particulate matter with a diameter less than 2,5 micrometers.
The sensor :
This sensor is based on an SDS011 PM2.5/PM10 laser for accurate and reliable air quality testing. This laser measures the level of particles in the air between 0.3 and 10 m.”
