Field Evaluation of Low-Cost Air Quality Sensors

· AQ-SPEC evaluates low-cost air quality sensors under ambient conditions through a field deployment at a SCAQMD air monitoring station (AMS). Sensors are typically tested as off-the-shelf products without prior modification, or calibration (zero, span, and accuracy). Sensors are operated according to the sensor manufacturer’s user guide or manual. If specified by the sensor …
