Telejointmeters and a temperature sensor that is operated with the WRLog radio data transmissio network.
- Telejointmeter for displacement measurement over individual fissures, convergence extensometer for distances over 1m to approx. 4m and over large distances between widely spaced boulders using laser distance meters
- Water pressure sensors for measuring pore water pressures groundwater levels, which often have a significant impact on rock and ground movements
- Inclinometers are used to detect tilt of rock structures and supporting structures (retaining walls, nail walls, etc.) with high precision.
- Borehole extensometers record shifts in soil and rock over one or more sections in the rock and ground
- Load cells allow monitoring of soil anchors and rock nails.
- Inclinometer measuring chains record and monitor deep sliding movements in vertical and horizontal
- The nodes are data loggers which transmit the measured values to the gateway using LORA radio. We can assume transmission distances of several kilometers and a battery operating time of several years. This eliminates the need for complex cabling work and the otherwise necessary surge protection.
- The gateway connected to the power supply is the receiver for the nodes and sends the data to an FTP server on the Internet. The data can also be queried via API.
The Huggenberger-Monitor web platform is prepared as a project website and provides the measured values graphically and numerically, can trigger alarms (as SMS or email) and summarizes the entire monitoring information on a password-protected website.
