1  · Light scattering low-cost particulate matter (PM) sensors have the potential to accurately monitor coal dust concentration in real time. The low cost, small size, and low power requirements of these sensors offer the promise of being widely worn by all coal mine workers. These could yield accurate concentration information if properly calibrated.
