Assessment of Three Wireless Sensor Network-Inertia Measurement Unit Devices for Landslide Monitoring
Publication: Geo-Congress 2020: Engineering, Monitoring, and Management of Geotechnical Infrastructure (GSP 316)
ABSTRACT
Three inertia measurement unit devices (denoted as Sensors A, B, and C) from different manufacturers were systematically evaluated for their performances in terms of data stability, reliability, and accuracy. A series of laboratory still, constant rotation, and platform tilt experiments were completed to assess the performances of these sensors. Still experiment was performed to compare the data noise from each sensor device, while platform tilt experiment was used to understand and verify gravitational acceleration readings in three-dimensional space at different slope angles. The constant rotation experiment was used to understand and verify gyroscope readings based on their orientation and the direction of rotation. Sensor selection for landslide monitoring application was conducted by comparing the pros and cons of the sensors as well as their capabilities. This study concludes that Sensor C provides the most accurate and reliable data with the least noise for slope movement monitoring.
