If you’re curious about your own neighborhood’s air quality, you can also build your own air sensor! The video above shows you how to build a DIY air sensor from a Raspberry Pi computer. You can learn more about the project from Pimoroni as well: learn.pimoroni...
Several studies have made use of similar DIY air sensors, like this study measuring black carbon in Oakland, or this project measuring air pollution around the world. Graeme Carvlin (featured in the video) even built his own network of air sensors to study air pollution in Imperial County in Southern California.
