[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 ...

This application note will show how all the colors within the color gamut formed by red, green, and blue constants in a CIE plot can be measured and mapped with an RGB color sensor. This RGB sensor ...

Abstract—Reflective color sensing is typically realized through pho- todiodes with multiple illuminants or photodiodes coated with color filters containing a single illuminant. This paper presents the ...

My husband and I recently bought a house built just after World War II with rooms stuck in nearly every decade since. I couldn't wait to get my hands on it and make it our own. However, picking the ...

Back in May, I wrote about Piper Computer and its simplicity in bringing Rasberry Pi to students. I loved the entire process of building and using the original Piper Computer. Today, Piper is ...

In this module we will be wiring a TCS34725 color sensor to our Raspberry Pi. We will use this sensor to measure raw RGB values, color temperature, and illuminance. We will then periodically print ...

How sensors are driving predictive maintenance. How maintenance is traditionally performed and the importance of moving to a data-driven approach. An overview of how sensors are the eyes and ears of ...
