Landslide early warning system based on arduino with soil movement and humidity sensors

Abstract

In this paper, a landslide monitoring system was built to detect the movement and humidity of the soil that generally causes landslides. The soil movement sensors utilizes a sliding potentiometer that converts distances into stresses and a humidity sensors. Data from sensors processed using a 10 bit Analog to Digital Converter (ADC) on the ATmega8535 microcontroller. The value of soil movement and humidity then sent digitally via serial USB communication protocol. The soil movement and humidity is displayed through the website interface in the form of graphic data and can be downloaded in the form of excel files. The results obtained through the simulation that the system is able to measure the movement of soil, soil moisture, and provide early warning through sirens. The system has a 1 mm resolution specification with a range of motion measurements with a linear correlation of 0.998. The system can also recognize sudden ground movements as an indication of landslides.
