Dust Networks Inc. (Hayward, Calif.) last week unveiled the world's first system-on-chip (SoC) for wireless sensor networks at Electronica in Munich, Germany. By integrating hardware and software functions to put distributed sensor networks on a single chip--called mote-on-chip--Dust Networks claims 5x lower power consumption than ZigBee, the elimination of the need for wired routers and a tenfold reduction in the overall price of adding new sensors to an existing network. Wireless sensor networks enable industrial users with distributed process control problems to quickly deploy new sensors without having to run cables to them, reducing their overall cost from thousands to hundreds of dollars. Emerson Process Management has launched a family of low-power wireless sensor networking systems that use Dust Networks' Time Synchronized Mesh Protocol (TSMP), including temperature sensors, pressure sensors, fluid-level sensors and fluid-flow sensors. British Petroleum (BP), Emerson's beta tester, now says that going wireless has reduced the cost of adding new sensors by 10x.
