In a simple network, the measurements
are transmitted directly to the computer.
Wireless Sensor Networks
e CR206, CR211, and CR216 can be used in a wire-
less sensor network. Wireless sensor networks are ap-
pealing because they are o en more economical than
trenching, laying conduit, and pulling wire. In some
applications, cabled sensors are impractical due to
man-made or natural causes, including construction,
lightning, moving platforms, agricultural production,
or bodies of water.
e diagrams at the top of the page depict our CR206/
RF401-based wireless sensor networks. Our CR211/
RF411-based and CR216/RF416-based networks are
similar. All wireless sensor networks require Logger-
Net 2.1 or higher so ware. e base datalogger must
use the PakBus communication protocol (e.g., CR800,
CR850, CR1000, CR3000). e PakBus protocol was
optional for our retired CR510, CR10X, and CR23X
dataloggers; the PakBus operating system is available,
at no charge, from www.campbellsci.com/downloads
for these dataloggers.
Other Applications
Aquaculture• —monitors and records water quality
around the clock providing continuous data that can
be used to identify trends and improve production.
Rural• Water —provides continuous monitoring
of the water system regardless of time of day or
time of year. All monitored sites can be net-
worked into one integrated system.
Water Level/Flow• —measures level in many envi-
ronments including wells, dams, streams, weirs, and
water treatment or wastewater treatment plants.
Compatible with sha encoder, pressure transduc-
ers, compact bubblers, radar water level sensors,
and sonic ranging sensor.
Water• Quality—monitors and records water
temperature, pH, dissolved oxygen, and turbidity.
Wind• Energy—can be deployed in a wireless
network con guration to provide cost e ective
monitoring at each level of a wind assessment
tower while avoiding long cables.
