TechBits: Node (01.23)

At the Consumer Electronics Show, the Tech Guy got to meet with the creator of Node. {}Node is a hand-held multi-purpose sensor. {}It's built around a transmitter unit, which connects to your smart phone or other mobile device using Bluetooth. {}A variety of sensor units can be attached to both ends of the transmitter. {}They can measure everything from motion to temperature to colors.

Some of the sensors have industrial applications- but sensors for temperature and color can be used in many consumer-level applications.

To use Node, you'll need a late-model mobile device equipped with Bluetooth version 4.
