Abstract
A moisture detector can include a first elongated conductor disposed on a substrate. The first conductor can define a zigzag path between the opposite ends thereof. A second conductor can also be disposed on the substrate at least partially surrounding the first conductor. The second conductor can define between opposite ends thereof a zigzag path having a portion thereof that is positioned in substantially spaced parallel relation with the zigzag path of the first conductor along the sides thereof. A power conductor disposed on the substrate can be electrically connected to the first conductor intermediate the ends thereof via a gap defined between the ends of the second conductor. Ground conductors disposed on the substrate can be electrically connected to the ends of the second conductor. A temperature sensor can be utilized to correct the response of the moisture detector for temperature.
