Review of sensors for air quality monitoring

quality of lowcost sensors is often questionable. It is affected by atmospheric conditions, pollutant concentration levels and therefore by the site location where the measurements are carried out. This report presents the collected results of quantitative studies of the performance of lowcost sensors against reference measurements. The information collected was an attempt to assess the ...

Analysing the performance of lowcost air quality sensors ...

· Lowcost sensors (LCS) are used to collect realtime air quality data providing highresolution spatial and temporal air quality data. These type of sensors are the new trend in air quality monitoring and can support the conventional air quality monitoring stations to increase the density of the sensing network (Heimann et al. 2015 ; Van den Bossche et al. 2015 ; Viana et al. 2015 ).

Evaluation of LowCost Sensors for Ambient Monitoring

Lowcost sensors are an opportunity to improve the spatial and temporal resolution of particulate matter data. However, such sensors should be calibrated under conditions close to the final ones before any monitoring actions. The paper presents the results of a collocated comparison of four models of lowcost optical sensors with a TEOM 1400a analyser.

Lowcost sensors for monitoring air quality | NILU

Lowcost air pollution sensors are attracting more and more attention. They offer air pollution monitoring at a lower cost than conventional methods, in theory making air pollution monitoring possible in many more locations. Too good to be true? At the current stage of development, unfortunately we have to conclude yes. Measurements with lowcost sensors are often of lower and more questionable data …

Review of sensors for air quality monitoring

A growing number of companies started commercialising lowcost sensors (LCS) that are said to be able to monitor air pollution in outdoor air. One benefit of the use of LCS is the increased spatial coverage when monitoring air quality in cities and remote locations. Today, there are hundreds of LCSs commercially available on the market with a cost
