GeoNet 8900 Series Wireless Data Hosting System | Model 8900 Series

  • The Model 8900 Series includes the VW Mesh Node, Addressable Mesh Node, Tiltmeter and Mesh Supervisor (top, left to right), the 4- and 8- channel 
VW Mesh Nodes and the Cellular Gateway + Mesh Supervisor (bottom, left to right).
  • The Model 8900 Cellular Gateway + Mesh Supervisor (left) is used to control the network, collect all sensor data from any Nodes deployed and seamlessly connect to the cloud server and hosted data platform. The Model 8900 Mesh Supervisor (right) provides the same network capabilities, but without cloud integration for secure, localized access to your sensor data.
  • The Addressable Mesh Node (left), used to connect GEOKON addressable sensor strings and addressable thermistor strings, and the self-contained Tiltmeter.
  • The 8900 Series Single-Channel VW Mesh Node (left), and the 4- and 8-channel Vibrating Wire Mesh Nodes (right), which expand the capacity at each node, 
allowing clusters of closely spaced sensors (up to 4 or 8 vibrating wire sensors respectively).
  • The 8900 Series 4- and 8-channel Nodes also provide the ability to add 3- or 6-gauge vibrating wire load cells (plus one or two additional sensors), multipoint borehole extensometers and multilevel piezometers to the system.
  • Typical GeoNet network, with line-of-site obstructions.

Model 8900 Series

The GeoNet 8900 Series is a low-power, wireless data acquisition system and hosted data platform. The integrated system affords the efficient collection of sensor data from many points and provides secure access to sensor data via the Internet and GEOKON OpenAPI. The system is especially useful in geographically complex locations where a wired infrastructure would be costly, or impossible, to install and difficult to maintain. The 8900 Series comprises single- and multichannel Vibrating Wire Mesh Nodes and Addressable Mesh Nodes to read all GEOKON vibrating wire and addressable sensors, respectively. Self-contained Tiltmeters are also available, for attachment to structures, to wirelessly measure any tilting that may occur. The multichannel VW Mesh Nodes expand the capacity at each node, allowing clusters of closely spaced sensors or vibrating wire load cells, multipoint borehole extensometers or multilevel piezometers to be added to the system. The system is compatible with all GEOKON Vibrating Wire instruments, addressable¹ sensor strings and addressable thermistor strings. A Cellular Gateway + Mesh Supervisor controls the network, collects all sensor data from any nodes deployed and provides seamless and secure cloud integration, which is achieved via GEOKON OpenAPI. GEOKON Agent software or optional third party software² may be used for secure data access and visualization via the Internet. A Mesh Supervisor, without cellular capabilities or cloud integration, provides the same control over the network to allow secure, localized access to your sensor data. The network is self-healing and will reconfigure itself, if possible, to tolerate disturbances to the physical environment. This topology is more flexible than star networks, in that communication can be established around obstructions. Up to 12 networks can coexist by setting each to a different operating frequency (channel).

¹Addressable MEMS, VW and Thermistor strings.
²Third party OpenAPI software options available soon.
