The core activity of AirVeraCity is the development and deployment of mobile air quality sensors installed on city buses to create high-resolution air quality maps in real-time. These sensors capture various air pollutants such as NO2, PM1, PM2.5, PM10, O3, CO, VOC, SOx, LDSA, temperature, and humidity. The collected data is used to provide accurate and localized air quality information, which is useful for urban planning, traffic congestion management, public health, and other applications.
