Abstract: Structural health monitoring applications aiming at the early warning to reduce the damage due to sudden collapsing are ledged thanks to the rapid development of circuitry and sensing devices. Recently, Semtech long-range (LoRa) wireless communication technology allows to facilitate the development of data communication network over a large-area, improving sensing reliability, extending battery life as well as reducing total system costs. This work presents the design and deployment of a LoRa-based structural health monitoring system. The vibration and displacement parameters being read from innovative MEMS sensors were uploaded to a real-time database server for analysis and evaluation. In addition, for the sake of providing information to the public, a web page is also developed to provide an interactive map composing obtained sensing values and corresponding charts. A case study on an actual health monitoring system for two major bridges in Can Tho City, Vietnam was conducted for validating the feasibility of the system.
