A moisture detection sensor is used in a building structure to detect moisture penetration. Systems and methods incorporating electronic valves, configurations of multiple check valve assemblies, and modules of valve assemblies are also provided herein. A configuration file further specifies parameters of the test statements, in terms of maximum elements, weights of different elements, etc. The first component is configured with a condensation surface and a heat-removal surface. In a particularly preferred embodiment, the polytrimethylene ether glycol is derived predominantly from monomers obtained from renewable resources, making the personal care products of this embodiment of the present invention more environmentally friendly in terms of their manufacture, use and disposal.
