Can your Plantower PMS5003-based Air Quality Sensor Measure PM10?

No. Let's investigate. The Plantower PMS5003 is a low-cost particle sensor that does a (very) good job measuring the total scattered light for particles that are able to physically make it to the sensing area of the device. The peer-reviewed literature has shown the PMS5003 is unable to detect particles

Empirically validating the air change rate (ACH) via the direct measurement of aerosols

While aerosol awareness has grown substantially in 2020-2021 (thanks to COVID-19), the direct relationship between ventilation rates and indoor aerosol concentrations remains somewhat less clear.  Here, we connect the dots between building ventilation and aerosols and demonstrate how low-cost particulate matter (PM) sensors can be used to empirically validate the
