QHAWAX is a small, low-cost module for continuous air quality monitoring designed for posts in urban areas with the aim of measuring urban air pollution. By providing a robust, autonomous, long-duration, and internet-connected equipment, qHAWAX contributes in the democratization of air contamination information for the general public. Through its technology, the following parameters for air quality are monitored: particulate material (PM2.5, PM10), carbon dioxide (CO2), sulfur dioxide (SO2), nitrogen dioxide (NO2), nitrogen oxide (NO), carbon monoxide (CO), pressure, temperature and relative humidity. Visual communication happens through the color of its indicator, in the shape of a leaf, which changes according to the Air Quality Index (AQI). Real-time information is made available through a 3G/4G mobile network. An important characteristic is its continuous 24/7 monitoring hours made possible using solar panels or the power grid.
