Laboratory evaluations of correction equations with multiple choices for seed low-cost particle sensing devices in sensor networks

To tackle the challenge of the data accuracy issues of low-cost sensors (LCSs), the objective of this work was to obtain robust correction equations to convert LCS signals into data comparable to that of research-grade i...

A versatile low-cost sensing device for assessing PM2.5 spatiotemporal variation and quantifying source contribution

This study evaluated a newly developed sensing device, AS-LUNG-O, against a research-grade GRIMM in laboratory and ambient conditions and used AS-LUNG-O to assess PM2.5 spatiotemporal variations at street levels of an As...

Concurrent Assessment of Personal, Indoor, and Outdoor PM2.5 and PM1 Levels and Source Contributions using Novel Low‐cost Sensing Devices

The intensity, frequency, duration, and contribution of distinct PM2.5 sources in Asian households have seldom been assessed; these are evaluated in this work with concurrent personal, indoor, and outdoor PM2.5 and PM1 m...

Panel study using novel sensing devices to assess associations of PM2.5 with heart rate variability and exposure sources

This work applied a newly developed low-cost sensing (LCS) device (AS-LUNG-P) and a certified medical LCS device (Rooti RX) to assessing PM2.5 impacts on heart rate variability (HRV) and determining important exposure so...
