An IoT sensor node for health monitoring of artwork and ancient wooden structures

In this work the authors propose an environmental monitoring system for artworks and wooden structures placed in museums and places of worship, based on smart BLE sensor nodes. The information about the artworks environment and their safety conditions are collected in real time and sent to a remote gateway. The developed nodes embed a temperature and humidity sensor, a barometer and a precision accelerometer with inclinometer. The nodes were developed to monitor the environmental factors which could compromise the health of the works in terms of biological and mechanical degradation. The small size of the proposed node, its low cost and its very low power consumption allows for the realization of pervasive monitoring systems, in the context of the IoT paradigm, with sensor nodes devoted to the monitoring of each artwork present in a museum or in a church.
