LEDs are a wonderful technology. You put in a little bit of power, and you get out a wonderful amount of light. They’re efficient, cheap, and plentiful. We use them for so much! What you might not ...

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 ...

I want to add an analog ambient light detector to one of my electronics projects. To do that, I picked the TEMT6000 ambient light sensor. TEMT6000 is a silicon NPN epitaxial planar phototransistor in ...

Scientists have developed a fully transparent skin sensor that accurately measures UV radiation, detecting light and converting it to electrical signals. So when the Sun's rays reach damaging levels, ...
