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 ...

It’s an unfortunate reality that for many of us, our air isn’t nearly as clean as we’d like. From smog to wildfires, there’s a whole lot of stuff in the air that we’d just as soon like to keep out of ...

We may receive a commission on purchases made from links. Dust collection is an absolute necessity for any woodworking, metalworking, or DIY craft that kicks up fine particles. Well-seasoned veterans ...

Technology may be shrinking, but its reach has never been greater. Devices that once filled entire rooms can now fit on the tip of a needle. This miniaturization is not just about space-saving; it’s ...

In computing, the vision always precedes the reality by a decade or more. The pattern has held true from the personal computer to the Internet, as it takes time, brainpower and investment to conquer ...

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 ...
