AbstractThis report describes the manufacturing and calibration of a compact temperature and relative humidity sensor. This study is part of a research project in the building envelope and structure program at the Institute for Research in Construction (IRC). The project included the testing of wall assemblies and components to determine their hygrothermal behaviour. Changes in moisture content (MC) and temperature of the materials undergoing evaluation were measured. Relative humidity (RH) and temperature that prevail in the air in the vicinity and at the surface of these components were also measured. Bulk MC was monitored by weighing the wall assemblies, while the distribution of moisture in individual component was monitored by using moisture pins inserted into the material at different depths and locations. The distribution of moisture depends not only on the properties of the material and the climatic conditions of the ambient air (temperature & relative humidity), but also on the micro-climate at the surface of the material.
