a communication device operatively coupled to the sensor;
an attachment element adapted to attach the leak detection system to an area for monitoring fluid leakage, wherein the attachment element is removable, reusable, or both, wherein the sensor comprises a detection element comprising an electrical circuit, and wherein the electrical circuit comprises a wire having a plurality of fingers; and
a substrate, wherein the detection element is in communication with the substrate, wherein the substrate is adapted to change between a first size when dry and a second size when wet in response to fluid contact, the first and second sizes being different from one another, and wherein the plurality of fingers are adapted so that a conductive fluid will bridge a gap between the plurality of fingers to create a closed circuit.
