The Geobrugg GUARD is a sensor system for rockfall barriers, debris flow barriers, avalanche prevention structures, and other protection measures. The small, robust device permanently collects and transmits environmental and physical data via the GSM network: Is there an impact or a load on the barriers like snow or debris? How long will the corrosion protection last? Does temperature or humidity play a role? You can see this and more on the online dashboard. The functional principle is explained in this video.
