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 ...

They’re tiny, wireless, battery-less sensors no larger than a piece of sand. But in the future, these “neural dust” sensors could be used to power prosthetics, monitor organ health and track the ...

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 ...

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 ...

Figure 1: Concept of a smart dust device using active transport by molecular shuttles. Controlled activation of motor-driven transport within the device relies on photolysis of ...

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 ...

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 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 ...
