Variable Inc., developer of the NODE modular wireless sensor platform, has released NODE+chroma, an affordable sensor module that provides instantaneous information about color scanned from virtually any surface. NODE+chroma transmits 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 include: DeltaE 2000 for color comparison, better than 0.80 deltaE reading-to-reading consistency, a measurement time of approximately one second, and a measurement area of 1.9 cm^2.
