Validation of Low-Cost Sensors in Measuring Real-Time PM₁₀ Concentrations at Two Sites in Delhi National Capital Region.

ABSTRACT: In the present study, we assessed for the first time the performance of our custom-designed low-cost Particulate Matter (PM) monitoring devices (Atmos) in measuring PM₁₀ concentrations. We examined the ambient PM₁₀ levels during an intense measurement campaign at two sites in the Delhi National Capital Region (NCR), India. In this study, we validated the un-calibrated Atmos for measuring ambient PM₁₀ concentrations at highly polluted monitoring sites. PM₁₀ concentration from Atmos, containing laser scattering-based Plantower PM sensor, was comparable with that measured from research-grade scanning mobility particle sizers (SMPS) in combination with optical particle sizers (OPS) and aerodynamic particle sizers (APS). The un-calibrated sensors ofte
