GeoNet is a battery powered wireless data acquisition network compatible with all of Geokon’s vibrating wire sensors. It
uses a cluster tree topology to aggregate data from the entire network to a single device - the network supervisor. GeoNet is
especially beneficial for projects where a wired infrastructure would be prohibitively expensive and difficult to employ.
The network consists of a Supervisor Node and up to 100 Sensor Nodes. Data collected at each node is transmitted to the
supervisor. Once there, it can be accessed locally via PC or connected to network devices such as cellular modems for
remote connectivity from practically any location. Features & Advantages…

Sensor Node
GeoNet Wireless network is self
healing and will reconfigure itself
to tolerate disturbances to the
physical environment.
This topology is more flexible
than star networks because it
allows data communication to be
established over longer distances
and around obstructions.

Long battery life. Most applications
measured in years.
When network connectivity
is re-established the data
collected while offline
will be transmitted to
the supervisor.
GeoNet Nodes are comparable in price to a single channel datalogger.
Uses worldwide 2.4 GHz ISM band.
Self configuring, easy installation.
GeoNet will automatically route data around obstructions.
Nodes separated from network will continue to collect and store data
autonomously.
All data collected
and sent to the
supervisor is also
stored on each
respective node. *Environmental factors also effect battery life
