Study and Characterization of LCPMS in the Laboratory

Atmospheric particulate matter or PM is one of the pollutants certainly most considered by professionals, both for the impact it has on the environment and for the impact, it has on human health. The official measurement methods for the detection of PM give information at long intervals and in pre-established sites giving a poor resolution from this point of view. For years, sensor manufacturers have tried to address this shortcoming with new portable devices, which have a very low sampling time (a few seconds) and a low price called the Low-Cost PM Sensor (LCPMS). This work shows a comparison of the performance of an LCPMS set. The test is carried out in the laboratory where a test chamber has been created capable of providing a controlled environment in which to test the devices.
