A Low-cost Air Quality Sensor for Measuring Particulate ...

The PurpleAir is a small, inexpensive device for monitoring atmospheric concentrations of particulate matter. While state-of-the-art monitors approved by EPA to monitor particulate concentrations for compliance with national air quality standards can cost $10,000 and up, the PurpleAir costs around $260. In addition, EPA-approved monitors require regular maintenance and calibration to operate and …

Review of sensors for air quality monitoring

A growing number of companies started commercialising low-cost 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

Analysing the performance of low-cost air quality sensors ...

· Low-cost sensors (LCS) are used to collect real-time air quality data providing high-resolution 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 Low-Cost Sensors for Ambient Monitoring

Low-cost 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 low-cost optical sensors with a TEOM 1400a analyser.
