Preparation and Characterization of Affordable Experimental Setup for Particulate Matter Sensing
Summary
A low-cost bench for testing particulate matter sensors, with a home-made generator that makes particles from dry powder, liquid suspension or combustion, small laser sensors and QCM sensors for ultrafine particles. The QCM response depends on particle source, composition and size, shifts by up to 22% with humidity, and works best for small smoke particles, which the laser sensors struggle to see.
