Investigation of Low-Cost Sensors for Particulate Matter and Gases for the Application in Measuring Ambient Air Quality

• Low number of air quality monitoring stations available due to expensive measurement devices and high maintenance

• Few monitoring stations do not provide information on the spatial distribution of air pollutants

• Low-Cost sensors can prove the solution to measure the spatial and temporal variability of air pollution

• Small, mobile and cost-effective measuring sensors are offered

• These sensors could be used to map cities with the spatial distribution of air pollutants

• These sensors may not be as accurate as professional equipment, however, the quality of these sensors is constantly being improved

• Potential low-cost sensors available for air quality monitoring were investigated for their data quality
