Compact gas sensors for real-time urban air quality monitoring

Summary: The EU-funded PASSEPARTOUT project is developing compact, affordable gas-sensing networks using laser technology to detect toxic gases like NO2, SO2, CO, and more in real-time. These hand-sized sensors aim to be as common as CCTV cameras, potentially on every lamppost. Dr. Whelan-Curtin highlights the system's precision and spatial resolution, with hopes for widespread urban adoption and integration into Google Maps for real-time air quality monitoring.
