Air Quality Measurements and Real-Time Maps<\/h6>\n
\n

CREATE-AQI provides real-time PM2.5 (particulate matter smaller than 2.5 um in diameter) maps through a university-run website (AQandU<\/a>) or though the Salt Lake County Health Department<\/a>. Dust (PM10, particulate matter smaller than 10 um in diameter) and additional counties will be coming soon. These maps are based on UDAQ and low-cost sensor measurements. We remove outliers, apply appropriate correction factors to low-cost sensor measurements, and we present the results in an easy-to-interpret heat map.<\/p>\n

The vast majority of low-cost particulate matter (PM) sensors are incapable of effectively measuring dust (PM10) in spite of manufacturer claims. Our team identified a cost-effect sensor for measuring dust (see publication<\/a>) and worked with TELLUS<\/a> to integrate this sensor into the sensor network. As part of this project, we will be working to optimize mapping for dust, which is more spatially heterogeneous (larger\/denser and tends to settle quickly) than PM2.5.<\/p>\n<\/div>\n<\/div><\/div><\/div><\/div>

Air Quality Sensors<\/h6>\n
\n

Air quality is measured in real-time using an air quality sensor network through TELLUS<\/a>. Each air quality sensor node is equipped with a TELLUS printed circuit board (PCB) and, at minimum, a sensor that measures PM2.5 and a sensor that measures temperature and relative humidity. Sensors placed outdoors may be equipped with an additional sensor that measures PM10, while sensors placed indoors will be equipped with an additional sensor that measures carbon dioxide.<\/p>\n<\/div>\n<\/div><\/div><\/div><\/div>

TELLUS device housing and PCB<\/h6>\n\nThe TELLUS PCB includes a microprocessor, WiFi or cellular antenna, and electronic equipment to receive air quality measurements from each sensor and communicate with and save the air quality measurements to an online database. Each PCB and set of air quality sensors is contained within a weatherproof housing unit.\n
