It is a low-cost variation of commertial wire extensometers for geotechnical measurements. To achieve this, it is based on 3D printed parts and a sensor by Waycon Positionsmesstechnik GmbH (though any other wire sensor also works). text/html 2023-02-02T14:27:18+00:00 Anonymous (anonymous@undisclosed.example.com) https://informatrisk.com/doku.php?id=en:monitoring_and_warning:lcostinclinometer&rev=1675348038&do=diff Low-Cost Inclinometer The general concept of the Low-Cost Inclinometer (LCI) is essentially the same as for the SMN, except that there are multiple inclination sensors attached. The inclination sensors are each 1 m apart and in total up to 4 sensors can be attached, resulting in an overall length of up to 5 m. The concept, including the wiring in the borehole/casing, is explained in the figure below. text/html 2023-01-16T15:56:11+00:00 Anonymous (anonymous@undisclosed.example.com) https://informatrisk.com/doku.php?id=en:monitoring_and_warning:mnodes&rev=1673884571&do=diff LoRa Measurement Nodes Introduction The Inform@Risk Measurement Node is the basis for all other sensors in the Inform@Risk measurement system. It is sometimes also referred to simply as 'Measurement Node'. In this document, the necessary materials and assembly of the basic Measurement Node are described.

This way, the system can be very versatile while keeping the cost low. The basic measurement node can simply be attached to walls to measure inclination or e.g. crack elongation with an external crackmeter (figure below). In this case, we call it 'Infrastructure Node'. When subsurface sensors are attached to it, we call it 'Subsur… text/html 2023-01-24T12:05:18+00:00 Anonymous (anonymous@undisclosed.example.com) https://informatrisk.com/doku.php?id=en:monitoring_and_warning:software&rev=1674561918&do=diff Software Installation for Measurement Nodes Introduction and Overview This document provides the necessary steps required for the installation and configuration of the Inform@Risk LoRa Nodes. The Inform@Risk LoRaBasis software requires only open-source libraries and dependencies to be installed in order to setup the LoRa nodes.

The SMP is part of the Inform@Risk measurement concept, which also consists of individual measurement nodes (LoRa Measurement Node) and deeper subsurface nodes (Low-Cost Inclinometer, LCI), which are explained in two additional documents, which can be accessed
