A dust sensor is an optical electronic system to detect fine particles such as dust. In principle, an optical dust sensor detects the dust particle concentration the in air by using an optical sensing ...

Fine dust pollution triggers all manner of health problems, but accurately tracking its concentration across cities and regions takes considerable manpower. That could get a whole lot easier with a ...

We’ve seen a lot of environmental monitoring projects here at Hackaday. Seriously, a lot. They usually take the form of a microcontroller, a couple sensors, and maybe a 3D printed case to keep it all ...
