[Fjord Carver] brings together an RGB LED and CdS Photoresistor to make a color sensor. Those Cadmium Sulfide lights sensors usually have a very wide swing of resistance when exposed to varying levels ...

Arduino color sorter project demonstrate the operations of sorting machines that are commonly used by industries. This project features an Arduino board and a color sensor that able to organize ...

[Rick Osgood] wanted to build a color sensor that could be held up to any object to get RGB color values. He originally started with a photoresistor and a few LEDs, but couldn’t get that to work ...

The Design Idea in Figure 1 is a color detector capable of generating an RGB triplet over a high dynamic range, a useful attribute for machine vision applications. The circuit implements auto-exposure ...

South African researchers have developed a new cleaning system for solar panels that uses a color-sensing light-to-frequency converter to detect dirt. It can reportedly remove around 95% of the dust ...
