The GeoNet 8800 and 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 (a secure, localized option is also available). 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 8800 and 8900 Series comprise single- and multichannel Mesh VW Loggers and a Mesh Addressable Logger to read all GEOKON vibrating wire and addressable sensors, respectively. Self-contained Mesh Tilt Loggers are also available, for attachment to structures, to wirelessly measure any tilting that may occur. The multichannel Mesh VW Loggers expand the capacity at each logger, 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 or Wi-Fi® Gateway² controls the network, collects all sensor data from any loggers deployed and provides seamless and secure cloud integration, which is achieved via GEOKON OpenAPI. GEOKON OpenAPI is easy-to-use and allows users to activate loggers, change settings, configure sensor channels, and view current logger status. Industry leading data visualization software, such as Vista Data Vision, or the no-cost GEOKON Agent Software, can be used with GEOKON OpenAPI for data viewing and reporting. A Local Gateway, without cellular or Wi-Fi 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).
The capacity of the Model 8800 and 8900 Series Multi-Channel and Addressable Loggers can be expanded using the Model 8960 Series GeoNet Digital Vibrating Wire Interfaces, and Solar Panels of various wattages are available.
