Particulates in the air are an important indicator of air quality, with proven health effects. At the surface level, they are characterized as particulate matter and their regulatory measurement is scarce or non-existent in countries with limited resources. That is why low-cost sensors represent a valuable alternative to acquiring this type of environmental data, but they have numerous limitations and must be properly characterized before use. A study of performance indicators of a low-cost optical sensor for particulate matter is presented, based on laboratory tests, simulations with a physical approach, and comparisons with calibrated equipment. Valuable information on sensor limitations was found and a control code was developed to warn the user of suspicious data.
