variations in large spatial scale regions. Deployment of such technology requires large number low-cost_x000D_
sensors. To monitor PM2.5 (suspended aerosol particles with an aerodynamic diameter no more than 2.5_x000D_
micrometers) distribution in a large area such as the urban area of a city, hundreds of low-cost PM2.5 sensors_x000D_
are required. Such sensors mostly are based on light scattering technology, and the readings were calibrated_x000D_
with standard aerosols by their manufacture. The calibration curves are only valid for certain aerosols under_x000D_
certain conditions (e.g., humidity, temperature, etc.), which makes their readings questionable when comparing_x000D_
with the results from mass or beta-attenuation -based technologies used by environmental monitoring agencies._x000D_
Therefore, there is need to calibration the low-cost PM2.5 sensors against the certified technologies by_x000D_
environmental authorities under the real-world conditions so that the sensor network could provide acceptable_x000D_
monitoring data for air quality assessment._x000D_
SensorUp is a leading sensor network provider based on IoT technology that has deployed an air quality_x000D_
monitoring network consisting of 200+ PM2.5 sensors to cover 75% of the area of metropolitan Calgary. The_x000D_
company is interested in an in-depth, quantitative study of the impacts of aerosols properties and_x000D_
meteorological factors on the readings of their sensors and developing a method to calibrate the sensors so that_x000D_
they can provide comparable reading with the certified instrument being used by Calgary Regional Airshed_x000D_
Zone (CRAZ). The outcome of this study will not only improve SensorUp's capacity in PM2.5 monitoring, but_x000D_
the method is also transferable to other instrument/pollutant providing environmental monitoring agencies and_x000D_
service providers a low-cost option for conducting high-resolution monitoring., program purpose french : The advancement of the Internet of Things (IoT) technology makes it possible for mapping air quality_x000D_
