5. The water detection device of claim 1 , comprising an additional power source electrically coupled to the electronic circuit and configured to provide electrical voltage to the electronic circuit for periodic testing of the electronic circuit.

6. The water detection device of claim 1 , wherein the passageways comprise openings disposed over the water-activated battery.

7. The water detection device of claim 1 , wherein the passageways are spaced a uniform distance apart from one another.

8. The water detection device of claim 7 , wherein the uniform distance is between 0.3 centimeters (cm) and 0.5 cm.

9. The water detection device of claim 1 , wherein a coating is disposed over the passageways, and wherein water is configured to dissolve the coating upon contact with the coating.

10. 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.

11. The water detection and notification device of claim 10 , wherein the water soluble layer comprises sugar glass, a water-soluble polymer, or a combination thereof.

12. The water detection and notification device of claim 11 , wherein the water soluble layer comprises the water-soluble polymer, wherein the water-soluble polymer comprises polyvinyl alcohol, polyvinylpyrrolidone, sorbitol, or a combination thereof.

13. The water detection and notification device of claim 10 , wherein the electronic circuit is disposed within a component housing configured to be disposed in an opening of the housing, wherein the component housing is modular with respect to the housing, and wherein the electronic circuit is removably connected to the water-activated power source.

14. The water detection and notification device of claim 10 , wherein the dormant power source has an anode comprising magnesium, aluminum, zinc, lead, thallium, manganese, silicon, iron, calcium, nickel, copper, or a combination thereof.

15. The water detection and notification device of claim 10 , wherein the dormant power source has a cathode comprising silver chloride, cuprous iodide, cuprous thiocyanate, lead chloride, cuprous chloride, or a combination thereof.

16. The water detection and notification device of claim 15 , wherein the cathode comprises a depolarizer.

17. 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.

18. The method of claim 17 , wherein the water is directed into the housing and toward the water-activated battery through adhesion, cohesion, surface tension, or a combination thereof.

19. The method of claim 17 , comprising dissolving a coating on a surface of a housing of the water detection device to expose the water-activated battery to water.
