Philadelphia launched a real-time air quality network with 76 solar-powered sensors to track pollutants and protect public health.
Philadelphia has launched the Breathe Philly air quality monitoring network, deploying 76 solar-powered sensors across all neighborhoods to provide real-time data on pollutants like PM2.5 and NO2.
The system, funded at $90,000 annually, offers color-coded air quality alerts via an online dashboard, helping residents—especially those with respiratory conditions—make informed decisions.
Sensors, spaced no more than 1.5 miles apart, are installed on utility poles and track pollution from vehicles, industry, and fires.
The initiative, overseen by the Department of Public Health, aims to improve environmental justice, support emergency responses, and guide policy, with potential future expansion to monitor ozone and benzene.
