Physical variables monitoring to contribute to landslide mitigation with IoT-based systems

Abstract

This document proposes the design of a low-cost platform that contributes to the monitoring of the physical variables involved in the process of generating land-slides through a low-power wide-area network. The system consists of three components. The first is the electronic module in charge of integrating sensors, sampling, digitizing, and sending data. The second is the LoRa wireless commu-nication system that links all the nodes located in strategic sites in the study area with the gateway, then the bidirectional messages (data) are sent from the gate-way to the server hosted in the cloud through the MQTT protocol, where all the data acquired from the sensor network and the web server are stored. The third component is the display of information to the user through HTTP requests from any multi-platform device. The platform generates a large amount of data that will serve as input for future investigations related to landslides. This design will al-low the generation of more reliable early warning systems.
