Air Quality and Environmental Justice

Everyone deserves access to a safe living environment and adequate resources to help address environmental concerns that arise—and that includes access to clean air. Air pollution is a huge health concern globally, and it disproportionately impacts our often already disadvantaged populations. Using tools including air quality (AQ) monitoring, scientists,

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

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
