Short summary
Optical-based particulate matter sensors offer some advantages: price (especially low-cost sensors), time and space resolution, but they are less accurate than reference instruments. Understanding their performance and limitations is crucial for wider adoption. This is a case study for strong and mild air pollution done in Sarajevo, Bosnia-Herzegovina. Tested optical sensors were found to be generally acceptable in this study, but proper calibration is required for getting reliable data.
