The D3S group has developed a WSN-based system to monitor the structural health of a medieval tower of Torre Aquila in Trento, Italy, part of the Castello del Buonconsiglio complex, which hosts world-renowned frescoes from the 13th century. The system has been running since August 2008, and monitors vibrations, deformation, humidity, and temperature.
D3S is a research group involving researchers from the Department of Information Engineering and Computer Science of the University of Trento and FBK-IRST.
The hardware platform and custom sensors for this project were provided by TRETEC. The project is in collaboration with structural engineers at the Department of Mechanical and Structural Engineering at the University of Trento, who are currently developing models to study the conditions of the tower based on the data provided by the system.
A live data feed from the sensors deployed is available, requires java enabled browser and some ports open in the network.
