What is an Intelligent Wireless Sensor ?

Specifics

Information

"Condition-monitoring applications can better accept the risk of an interrupted signal and stand to gain the most from the lower costs, so these sensors are getting their first industrial tryouts in maintenance and system-monitoring applications." - Rich Merritt, Plant Services Magazine

“One of the most immediate benefits of being able to deploy many inexpensive wireless sensors across a process is a heightened ability to make inferential measurements. Most process plants today take measurements at only about 10% of the possible points. Although they might get better results by taking measurements at more points, running the wiring and connecting the sensors is cost-prohibitive." - Hesh Kagan, Invensys Process Systems

"... the installed cost of the mote is about $1000, compared to almost $8000 for a conventional (wired) system." - Rich Merritt

... that gathers and transmits operational and environmental data to your key systems. It is called a 'mote' by the folks at UC Berkeley because by dictionary definition a mote is a small 'thing' and any other terminology is too long. More than one mote self-forming a network is called an Intelligent Wireless Sensor Network( iWSN ).

"Intelligent" means that the mote has adequate computing power to

a) collect data at defined intervals,
b) pre-process and consolidate that data
c) filter and transmit data to a central gateway
d) join with other motes in a "mesh" network
e) be re-programmed from a remote site to act under new instructions or parameters

Think of the old comparison of 'dumb' mainframe terminals to 'smart' PCs. The 'smart' product led to much more flexibility and usefulness.

The Mesh Network is a topology that allows the mote data transmission to use alternative paths to the network gateway.

In contrast, an RFID has limited if any intelligence and cannot be part of a network.
