The present subject matter relates to absorbent articles and signaling devices for use therewith. An absorbent article may be provided with selected electrical components used as wetness or other type sensors and may also incorporate one or more electrical components, characteristics of which may be determined by a coupled signaling device. An attached signaling device may automatically determine a product identification based on characteristics of the electrical components detected and adjust operating characteristics or parameters for the sensing device. Determinations could be made based on gender, age and approximate weight of the user of the absorbent device. In addition automatic checks can be made to determine mutual operability of the signaling device with an associated absorbent article or visa-versa.
