8910 Series Tilt Logger

The 8910 Series Tilt Loggers combine the capabilities of a biaxial MEMS tilt sensor with a wireless GeoNet Logger. The self-contained tilt loggers utilize LoRa radio technology and can be attached to various structures including dams, embankments, foundation walls, retaining walls, buildings, etc., to provide wireless measurement of any tilting that may occur. Remote access of sensor data is achieved via the Gateway, which controls the network and collects sensor data from any tilt loggers deployed.

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 this Tilt Logger. Please see the Model 8910 Series for more information about the full complement of GeoNet Wireless LoRa Loggers.
