Audrey Rappaport. Audrey worked on calibrating a low-cost particulate matter sensor--the Plantower PMS3003--against an MDE reference sensor--the BAM1020. While the BAM1020 has a heated inlet to dry out particles before measuring, the PMS3003 does not due to size and cost constraints. During times of high humidity, PM2.5 measurements from the PMS3003 tend to spike up as the hygroscopic growth (swelling with water) of the particles is uncorrected. Audrey developed calibration functions that took relative humidity into account in order to bring the PMS3003 measurements into better agreement with the BAM1020. See the poster of her work here.
Audrey graduated from the Clark School of Engineering at the University of Maryland in 2023 with a degree in mechanical engineering and is currently working in the engineering field.
