1. A fluid detection fabric, comprising:
a top layer, a middle layer, and a bottom layer, a first conductor attached to the top layer, and at least one stitch, wherein the at least one stitch is configured to direct the fluid from the top layer to the middle layer and from the middle layer to the bottom layer, wherein the top layer, the middle layer and the bottom layer are configured to connect utilizing the at least one stitch if liquid leaks on at least one of the top layer, middle layer, and bottom layer;
a fluid detection sensor having at least one second conductor connected to the bottom layer; and
a control hub having an input pin connected to the first conductor, the input pin configured to apply a first voltage supplied by the control hub across the top layer, an output pin connected to the second conductor of the fluid detection sensor, the output pin configured to measure a second voltage across the bottom layer, wherein the second voltage is the voltage across the bottom layer after the fluid is introduced to the fluid detection fabric;
wherein the fluid creates a conductive pathway from the input pin of the first conductor of the top layer through the middle layer to the bottom layer, electrically connecting the top layer to the bottom layer;
wherein the conductive pathway of the top layer to the bottom layer increases the second voltage across the bottom layer;
wherein the control hub is configured to detect the increase in the voltage across the second layer and detect the fluid by measuring a voltage reading of the second voltage using the output pin after the fluid is introduced.
