Buildings, bridges, pedestrian walkways, industrial structures, and lightweight infrastructure are continuously exposed to vibrations and mechanical stress. Traffic, wind, machinery, nearby construction work, ground settlement, and temperature variations can all generate movements that should be monitored and compared over time.
Periodic inspections remain essential, but they only describe the condition of a structure at the moment the inspection is carried out. A distributed IoT monitoring system adds a time dimension by continuously collecting data and identifying changes from the structure's normal behavior.
A compact structural monitoring device can integrate triaxial accelerometers, inclinometers, temperature sensors, and, when required, strain gauges or other transducers. The selection of components depends on the type of structure, the magnitude of the movements to be measured, and the frequency of the phenomena being monitored.
One of the most important aspects is data management. Continuously recording every vibration would generate large amounts of information, much of which would not be useful. For this reason, the device can process signals locally, identify significant events, and transmit only the indicators or event sequences that exceed predefined conditions.
Edge processing can calculate parameters such as peak acceleration, dominant frequencies, inclination, event duration, and deviations from the reference condition. These data can then be transmitted to a remote platform through cellular networks, LoRaWAN, or other communication technologies, depending on the installation site and the available communication infrastructure.
The long-term stability of the system is essential. A device installed on a bridge or building must withstand harsh environmental conditions, minimize power consumption, and maintain accurate time synchronization. The mounting method and sensor placement also have a direct impact on measurement reliability.
IoT structural monitoring does not replace the assessment performed by structural engineers and inspection professionals. Instead, it provides an additional tool to identify changes, correlate events, and determine when further inspections or specialized analyses are required.
Applications include small bridges, historic buildings, industrial facilities, pedestrian walkways, silos, towers, industrial plants, and temporary structures. In many cases, monitoring can begin with just a few sensing nodes, allowing collected data to be compared against known operating conditions.
TechCrafters develops custom hardware and IoT systems to acquire, process, and transmit data from buildings and infrastructure. Every project starts by defining the phenomenon to be monitored, the required measurement limits, and the environmental conditions, before progressing to a prototype and field validation.
