Urban Air Quality and Heat Island Monitor (SDG 11 / SDG 13)
A Raspberry Pi urban air quality monitor demonstrates how edge computing and low-cost environmental sensing can support neighborhood-scale climate adaptation, pollution awareness, and SDG 11: Sustainable Cities and Communities. This project combines a Raspberry Pi with a BME280 atmospheric sensor and PMS5003 particulate matter sensor to measure temperature, humidity, pressure, PM1.0, PM2.5, and PM10 while storing observations for later analysis. While the prototype is not a certified regulatory air-quality station, it shows how distributed monitoring can make urban heat islands, particulate pollution, and uneven environmental exposure more visible. The article connects the build to environmental monitoring systems, intelligent infrastructure, atmospheric aerosol risk, climate change, planetary boundaries, and sustainable development, showing how local data infrastructure can support healthier, more resilient cities.
