TLDR

The declining state of civil infrastructure has driven research into real‑time structural health monitoring using decentralized smart sensors, and the Intel Imote2 platform offers the computation and communication resources needed for such dense sensor networks. The study develops a versatile Imote2 sensor board with onboard signal processing tailored for real‑time structural health monitoring. Its accelerometer board components were chosen for low‑noise, high‑resolution data acquisition to support SHM algorithms.

Abstract

The declining state of civil infrastructure has motivated researchers to seek effective methods for real-time structural health monitoring (SHM). Decentralized computing and data aggregation employing <i>smart sensors</i> allow the deployment of a dense array of sensors throughout a structure. The Imote2, developed by Intel, provides enhanced computation and communication resources that allow demanding sensor network applications, such as SHM of civil infrastructure, to be supported. This study explores the development of a versatile Imote2 sensor board with onboard signal processing specifically designed for the demands of SHM applications. The components of the accelerometer board have been carefully selected to allow for the low-noise and high resolution data acquisition that is necessary to successfully implement SHM algorithms.
