Description
Precision geotechnical monitoring is vital for infrastructure safety, yet traditional manual methods for inclinometer measurements suffer from intermittent data collection, creating "temporal gaps" that hide potential failures. While commercial In-Place Inclinometer (IPI) systems offer continuous monitoring, their high cost and mechanical complexity make large-scale deployment unviable. The proposed solution establishes an economically viable alternative utilizing affordable, high-precision Micro-Electromechanical Systems (MEMS) sensors. This paper describes the development of a miniaturized sensor node built around the Murata SCL3300-D01 3D MEMS and the STM32G0F1 microcontroller. The solution replaces expensive rigid joints with a continuous multilayer flexible tubing system and introduces a 3D-printed "spider spring" centring mechanism. Preliminary results demonstrate the feasibility of a high-density, IoT-enabled sensor chain capable of providing real-time, high-resolution deformation data for critical geotechnical structures such as highway embankments and dams.
