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 ...

Schematic of a smart dust battlefield sensor network as depicted in the grant application for DARPA’s Smart Dust project: Thousands of sensor nodes covering square kilometers are delivered by ...

dust-free area to work in. Next step: Gain access to the sensor. To do this, you'll need to remove the lens and select a menu function called something like "Lock Mirror Up for Cleaning" (the ...

These are often the results of dust specks that have landed on your camera’s sensor, and they are a nuisance, but you can deal with them. Removing the dust digitally is fine for the occasional ...

That could get a whole lot easier with a sensor that attaches to a smartphone and measures particulate matter (fine dust) levels in the air, which is under development at the Karlsruhe Institute ...

For his build, [Richard] used a Sharp GP2Y1010AU0F dust sensor. This $11 device has a little hole, through which airborne dust particles can pass. On the inside, an infrared LED and a photodiode ...

Anti-static coatings on the sensor are designed to repel dust in the first place. Ensure you have a fully charged battery before cleaning your sensor; power is needed to keep the mirror flipped up ...
