Instant Color Scanning/Matching
This company has released the NODE+chroma, an affordable sensor module that provides instantaneous information about color scanned from virtually any surface. NODE+chroma transmits highly accurate color data via Bluetooth 4.0 to iOS smart devices up to 250 feet away.
The NODE+chroma module, which connects to the NODE sensor platform device, has an end cap that allows a perfect white LED light to compute true sRGB, CIE, L*A*b*, and Hex values, regardless of ambient light. Technical specifications: DeltaE 2000 for color comparison; measurement time is approximately 1 second; measurement area is 1.9 cm2.
