What's a modular sensor without modules? The folks behind Node have released the iPhone peripheral's fifth end cap, the NODE+chroma, a sensor that scans colors, transmitting that data to your handset via Bluetooth 4.0. The $99 add-on features white LED light, capturing a reading in around a second, regardless of the influence of ambient light. You can pick up the new module over at Node's site, along with climate, gas, thermometer sensors and an LED flashlight. And while you're at it, you should probably pick up the $149 Node as well, or those sensors won't be of much use.
