Measurement Design of Sensor Node for Landslide Disaster Early Warning System

摘要

Landslide is one of the most frequent disaster happened in Indonesia. It can occur due to some major factors, e.g.; high rainfall and soil moisture. In order to predict the occurrence of landslide disaster, data sensing system of these factors are acquired. A prototype of data acquisition is proposed. The prototype provides sensors for sensing of four parameters, which are MPU 6050 sensor, tipping bucket with reed switch, two of FC-28 humidity sensors, and 801s sensor, to measure slope, rainfall, moisture, and ground vibration, respectively. This system is also equipped with the process of data retrieval or log data in real-time with SD Card in the process directly and delivery via the server via SIM900. From the sensor test results, which are obtained from reading value of each sensor, the system shows low error values of 0.165, 0, 0, 0.39, and 0.71, for MPU6050, tipping bucket, 801S, and the two of FC-28 sensors, respectively.
