 AQ-SPEC 

The Air Quality Sensor Performance Evaluation Center, or AQ-SPEC, is a research and development group within the South Coast AQMD specializing in the use of low-cost air quality sensors.

The AQ-SPEC program aims at performing a thorough characterization of currently available “low-cost” sensors under ambient (field) and controlled (laboratory) conditions. Low-cost air monitors are increasingly popular, and advances in technology means everyone can play an active role in monitoring air pollution and contributing to improving air quality. The AQ-SPEC Program is an initiative by the South Coast Air Quality Management District (AQMD) which evaluates low cost sensors in controlled laboratory and field settings, and provides the public with information on the performance of these sensors.

Main Goals & Objectives Evaluate the performance of commercially available "low-cost" air quality sensors in both field and laboratory settings Provide guidance and clarity for ever-evolving sensor technology and data interpretation Catalyze the successful evolution, development, and use of sensor technology

Sensor Selection Criteria The sensor shall have potential for near-term use. The sensor shall provide real- or near-real time measurements. The sensor shall measure one or more of the National Ambient Air Quality Standards (NAAQS) criteria pollutants, air toxics, pollutants of concern and non- air toxics. Examples of the targeted gases and particles are carbon monoxide (CO), ozone (O3), nitrogen oxides (NOx), particulate matter (PM), volatile organic compounds (VOCs), hydrogen sulfide (H2S) and methane (CH4). The market cost of the sensor shall be less than $2,000. Turnkey products will be tested first.
