City of Lima
Lima
In 2020, Lima, Peru, in collaboration with C40 Cities, launched an initiative to combat air pollution and improve public health by implementing QHAWAX, an advanced air quality monitoring system. The project established the largest air quality network in Lima, covering 8 districts to gather precise data on pollution levels.
QHAWAX’s real-time data helps create effective strategies to tackle Lima’s air quality challenges. Alongside the monitoring network, the city also introduced a pedestrianization project to reduce vehicle emissions and improve urban mobility.
The initiative has raised public awareness, informed policy-making, and contributed to better air quality standards. Lima’s efforts position the city as a leader in Latin America’s fight against air pollution and a model for other cities.
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.
