Water detection assembly

A water detection and notification device, comprising:

• a housing;
• a multiple-layer wall of the housing, the multiple-layer wall defining at least one side of a chamber of the device;
• a water porous layer of the multiple layer wall;
• a water soluble layer of the multiple layer wall that limits or blocks access of water, contaminants, or both into the chamber through openings of the water porous layer;
• a material of a water-activated power source disposed within the chamber, the material changeable upon exposure to water from a dormant condition, in which no electrical voltage is generated by the water-activated power source, to an active condition, in which electrical voltage is generated by the water-activated power source;
• passageways formed in an external surface of the multiple-layer wall of the housing, wherein the passageways comprise channels configured to direct water into the housing toward the water-activated power source via capillary action;
• and
• an electronic circuit connected to the water-activated power source configured to transmit an electrical signal out of the device in response to a change of the material of the water-activated power source from the dormant condition to the active condition to indicate a water leak.

A method, comprising:

• linking a water detection device having a water activated battery and an electronic circuit with an electronic device;
• directing water into a housing of the water detection device via a plurality of capillary passageways disposed on an external surface of the housing, wherein the plurality of capillary passageways comprises a plurality of channels configured to direct water into the housing via capillary action;
• activating the water-activated battery upon exposing the water detection device to water;
• and
• reporting a detection event upon activation of the water-activated battery to at least the electronic device.
