Smart Zigbee Mesh Sensors

As sensors spread throughout buildings, and as controlling computers become cheaper and cheaper, the industry needed an easy and cheap way to move information from device to device. The ZigBee wireless protocol provides a mesh-based network, with smarts enough to route signals from dumb device to dumb device, at between $1 to $5 per unit. Think of it as a mesh-based two-way version of RFID.
