Smart dust goes on sale

SmartMesh Dust Networks Smart Dust

They're not really all that smart (yet) or as actually small as dust (yet), but smart dust just officially exited the lab and become a commercial reality. Dust Networks has begun selling their SmartMesh Evaluation Kit, which comes with 12 low-power radio-enabled "motes" which are basically sensors that collect data and then create a wireless mesh network to relay it back. The motes come with sensor plug-ins that can monitor temperature, light, and tilt, but eventually you'll probably to rig a smart dust sensor net to cheaply and easily keep tabs on pretty much anything that can be measured or detected.
