Landslides are catastrophic events that change the territory making these events dangerous for buildings and people. Monitoring and alerting on a possible landslide can avoid disasters and can save lives. Thanks to a monitoring system it is possible to prevent and intervene in time before the situation gets worse. The aim of this work is the design of a wired sensor monitoring system for landslide events. The system is composed by one datalogger and many nodes, which measure the inclination, and communicate between each other through RS485. The datalogger is based on a microcontroller ATmega2560 which has the task of retrieving data from nodes and sending them to an FTP server. The nodes have an ATmega328p microcontroller that reads data from a digital accelerometer MMA8451 that is able to detect inclination variations up to 0.1 degrees.

Abstract

Landslides are catastrophic events that change the territory making these events dangerous for buildings and people. Monitoring and alerting on a possible landslide can avoid disasters and can save lives. Thanks to a monitoring system it is possible to prevent and intervene in time before the situation gets worse. The aim of this work is the design of a wired sensor monitoring system for landslide events. The system is composed by one datalogger and many nodes, which measure the inclination, and communicate between each other through RS485. The datalogger is based on a microcontroller ATmega2560 which has the task of retrieving data from nodes and sending them to an FTP server. The nodes have an ATmega328p microcontroller that reads data from a digital accelerometer MMA8451 that is able to detect inclination variations up to 0.1 degrees. Furthermore, the nodes are able to go into sleep mode reducing power consumption. The system includes a calibration phase for the first installation on site to be monitored. The proposed system was tested in a real case and same preliminary data, obtained after a post processing done with Matlab, are here reported.
