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 ...

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 ...

Imagine a cloud of sensors, each the size of a grain of sand or even smaller, blown aloft by hurricane winds and relaying data on the storm to weather stations below. Picture an invisible sensor ...

In 1997, while a professor at the University of California at Berkeley, Kris Pister proposed a project to deliver sensing, computing and networking in a millimeter-sized package. The project, called ...
