The 8921 Cellular Tilt Data Logger is ideal for smaller, LTE Cat 1 compatible networks with a limited number of sensors, high-traffic areas (i.e. areas with radio interference), dense urban environments and areas with no line-of-sight between loggers.

GeoNet Cellular¹ Tilt Data Loggers can be added to sites with existing GeoNet 8800 Series and/or GeoNet 8900 Series Wireless Data Hosting Systems, allowing tilt readings to be taken in locations that are beyond the range of the existing network.

Seamless and secure cloud integration is achieved with GEOKON OpenAPI. The GEOKON OpenAPI portal 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, or the no-cost GEOKON Agent Software, can be used with GEOKON OpenAPI for data viewing and reporting.

In addition, Solar Panels of various wattages are available for use with these Tilt Data Loggers.

For more information about the full complement of GeoNet Cellular Network Data Loggers, please see the GeoNet 8921 Series.

¹GeoNet Cellular Gateways are compatible with all major networks except Verizon.
