11/12/2024: Optimizing Calibration Methods for Low-Cost PM2.5 Sensors in High-Concentration Occupational Environments

Recorded on Tuesday, November 12th, 2024

Webinar Navigation

About the webinar:

Fine particulate matter, also known as PM2.5, poses significant health risks to humans, such as heart disease, lung-disease, and cancer. Occupational environments are especially prone to high concentrations of PM2.5, which makes monitoring air quality essential to the health and safety of workers. This webinar will present the results of a study assessing the calibration precision of low-cost PM2.5 sensors, using Linear Regression (LR), Random Forest (RF), and Polynomial Regression (PR) models across various concentration ranges of fine particulate matter.

Learning Objectives

The specific objectives of this research are to: 

  • Evaluate the accuracy of LR, RF, and PR models at higher PM2.5 concentrations
  • Assess the performance of LR, RF, and PR models in these conditions 
  • Recommend the optimal calibration approach for low-cost sensors used in high-concentration environments

Speaker: Runcheng Fang, PhD Candidate

Runcheng Fang is a PhD candidate in the Industrial Hygiene Program at the University of Utah, specializing in air quality monitoring and sensor calibration. Her research focuses on improving the accuracy of low-cost PM2.5 sensors using machine learning and environmental assessments. Runcheng has extensive experience in exposure assessment and environmental toxicology, contributing to projects such as the Environmental Influences on Child Health Outcomes (ECHO) and UCOVER. She has presented her work at national conferences and received multiple scholarships for her contributions to industrial hygiene and occupational health research.
