The first air quality monitoring station of GATE City Living Lab is installed near the zoo in Sofia city.
It is equipped with four electrochemical gas concentration (CO, NO2, O3, SO2) sensors and a particulate matter sensor using laser-scattering technology to detect particles (PM1, PM2.5 and PM10).
The station also provides measurements of ambient temperature, relative humidity, pressure, CO2 concentration, levels of precipitation, wind speed and direction, and noise levels.
Additional 11 stations are in process of installation.
