Therefore, efforts in research, warning, and prevention of landslides have been made at different scales. One of the conditions that triggered landslides is the sudden rise of the rainfall. This paper focuses on building a low-cost rain gauge, which consists of an electrode sensor and a microcontroller board. Alert threshold is determined based on statistical methods in several years to give a timely warning. The system has been successfully built and tested in real experiment. %C Hanoi %D 2018 %L SisLab3117
