Finding F-0250

“We lost more Airbeam 1 sensors (N = 27 out of 56, failure rate 48.2%) than Airbeam 2 (N = 2 out of 24, failure rate 8.3%) due to electronics, battery, or data output issues.”

Structure

Source: Tobacco smoke (secondhand smoke)
Factor: Particulate matter (PM₂.₅ and PM₁₀)
Method: Low-cost sensors
Study design: longitudinal performance study of 51 low-cost particle sensors (Airbeam 1 and Airbeam 2) calibrated four times over two years (2019-2021) against a Thermo Scientific PDR-1500 with cigarette smoke (class 4)
Effect: other 48.2
Caveat: failures due to electronics, battery or data output issues
