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

Use py-smps to analyze size-resolved particle sensor data

py-smps is an open-source python package to help analyze and visualize data from aerosol sizing instruments such as the Scanning Mobility Particle Sizer (SMPS), Scanning Electrical Mobility Spectrometer (SEMS), and other aerosol-sizing instruments such as optical particle counters (OPCs). While it was originally developed to analyze data from research-grade instrumentation,

Rebasing time series in python

Quite often, you may find yourself with two sets of data - both time series - that do not share the same time index. There are a couple of common use cases where this may arise in air pollution/atmospheric chemistry: 1. You have two instruments that collect data at

AAAR 2021

The 2021 American Association of Aerosol Research conference is currently taking place in Internet-land. If you're attending and interested in learning about how QuantAQ's low-cost, professional-grade air quality sensors can be used to understand building ventilation, sources of urban air pollution, or be used to help

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

Hello, Air Quality World!

Hello, Air Quality World!

Welcome to the QuantAQ blog! We founded QuantAQ in 2019 as a spinout of MIT and Aerodyne Research, Inc. We realized that the most efficient path to obtaining ubiquitous air quality monitoring was to move our research outside academia and build a team to combine modern computational data science with
