A structure includes a structure surface and a protective cover. The protective cover includes a circuit having a component, a moisture detector, and a radio frequency transmitter. The component is adhesively connected to the structure surface with an adhesive connection. The moisture detector is positioned to provide information about moisture in the protective cover. The circuit is for providing data derived from the component and from the moisture detector to the radio frequency transmitter for external transmission. The component may be a strain sensor. The moisture detector may be a capacitor. A moisture barrier may also be provided. |
