High Density Sensor Network Inside Bus Terminus to Monitor Air Quality for Hotspot Identification

The air quality inside the semi-enclosed bus terminus has been a great challenge in urban settings. Sapiens air sensors (NAS-AF300) is used in Hong Kong by government agencies to closely monitor the air pollutants of NO, NO2, CO, CO2 and PM2.5 from traffic emission inside the bus terminus. The high-density network creates a real time air pollution map to identify the hotspot of air pollution and diagnose the critical causes of the air pollution issues. It also helps to evaluate the effectiveness of the mitigation measures.

MAS-AF310

MAS-AF310 is the flagship model of Sapiens Mini Air Station (MAS) series products for high performance and long-term outdoor air quality monitoring with integrated autonomous data quality control capabilities. The product can measure criteria air pollutants including particulate matters (PM₁, PM₂.₅, PM₁₀, TSP), nitrogen dioxide (NO₂), ozone (O₃), carbon monoxide (CO), sulphur dioxide (SO₂), nitric oxide (NO) and carbon dioxide (CO₂) with near reference data quality under all weather conditions, and total volatile organic compounds (TVOC) at high accuracy.
