Application of a novel monitoring technology at “Minerva Medica Temple” archaeological site in Rome

Environmental parameters monitoring is necessary to preserve materials, identify causes of degradation, and quantify their effects, as a function of time. In this research, we propose a measuring unit and present an example of collected data. The unit is based on an ATmega328P microcontroller, gathering signals from: a 9-axis MIMU; a sensor for temperature and relative humidity; and three gas detection miniature boards (NO, NO2 and SO2). The aim of the project is to monitor effects of different factors: (i) seasonal thermal variations; (ii) dynamic response of the structure and (iii) gaseous pollutant concentration. The developed system allows for a prioritization of intervention both for organization and management, and for interventions planning in terms of restoration, consolidation, and conservation.
