A community-assembled sensor mesh mapping Lahore's air street by street: 140 locally-built PM2.5 monitors on rooftops and school buildings, calibrated quarterly against reference stations, publishing open hyperlocal data. Schools use sensor-triggered indoor-day protocols; the map logged 4M views last smog season.
