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 ...
Figure 1a shows a slotted optical switch. An LED is mounted in a plastic housing, facing a phototransistor, but separated by a gap. If something moves into the gap, it blocks the light path between ...
A research team led by Professor Jiwoong Yang of the Department of Energy Science and Engineering at DGIST has developed next-generation optical sensor technology capable of precisely detecting not ...
Health conditions caused by fine dust pollution have been highlighted in recent reports from big cities such as Beijing and, more recently, Paris. But if you wish to know about the scale of this ...
Optimizing office environments Infrared sensors that measure mean radiant temperature better reflect the heat levels that individuals perceive. (Courtesy: iStock/AntonioGuillem) The internal ...
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 ...
