Networked Mems Pressure Sensor System For Landslide Detection

Abstract

This paper presents the design and implementation of a Networked MEMS Pressure Sensor System for real-time landslide monitoring and early warning. The proposed system employs two MEMS-based pressure sensors installed at different locations to continuously measure pore water pressure and assess ground stability. A raindrop sensor is incorporated to detect rainfall intensity, while a flow sensor monitors surface water flow—both of which are critical parameters influencing landslide occurrence. Upon detection of rainfall, the system activates continuous pressure monitoring. If abnormal or rapid changes in soil pressure are detected, indicating potential slope failure, the system triggers a local buzzer alarm and simultaneously transmits alert messages to concerned authorities via a GSM communication module. An LCD module displays real-time sensor data, and the entire system is controlled by an Arduino microcontroller for efficient data processing and coordination. This integrated sensing and alert framework provides a cost-effective, scalable, and reliable approach to landslide risk detection and early warning.
