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 ...

The SM-PWM-01-A (527-SM-PWM-01A) is a smart dust sensor featuring a constant forced air convection typically used for dust detection in air and indoor air quality monitoring. It can detect a particle ...

Out of sight might mean out of mind, but it doesn’t necessarily mean out of danger, particularly in the case of small airborne particles. Such particles can severely affect your health, with effects ...

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 ...
