| This system was developed to prevent work accidents caused by landslides and rockslides. The system is based on precipitation monitoring and recording according to the "Revised Labor Safety and Sanitation Guidelines". It is used in combination with extensometer Data Loggers and wire sensors so that alarms can be issued. The principal units can operate for a long time on lithium batteries, forming a system that can be used in locations where there is no commercial power supply. |
