| Research Abstract |
It is important to understand the water content and evaporation on the surface of mural paintings in order to prevent from exfoliation of pigments, deposition of salts, fungi growth and so forth. However, there have not been many researches because non-invasive measurements in high-humidity environment are difficult.
In this study, a measurement system was first constructed using two small data-loggers. Evaporation on the surface of the stone was identified from the gradient of absolute humidity calculated from measured values of temperature and relative humidity. One of the drawbacks of this method is that the data-logger is poor in humidity resistance. Temperature and humidity sensors, which have better humidity resistance, were selected to develop a new system for application at humid sites. It is composed of a control board Arduino Mega 2560, which controls the digital signals from sensors and records the data on a micro SD card. A prototype system was evaluated in this study.
