[0006] In some embodiments herein, the IO threads are pulled to high by an internal pull up resistor of the IOT device and a value of IO port will be “1” when the reusable wetness detection sensor is dry.
[0007] In some embodiments herein, the IO threads are pulled to high by an internal pull up resistor of the IOT device and a value of IO port will be “0” when the reusable wetness detection sensor is wet.
[0008] In an aspect, the embodiments herein provide a method for wetness detection using a reusable wetness detection sensor.

BRIEF DESCRIPTION OF THE DRAWINGS
[00012] The embodiments herein will be better understood from the following detailed description with reference to the drawings, in which:
[00013] FIG. 1 depicts a reusable wetness detection sensor, according to some embodiments as disclosed herein;
[00014] FIG. 2 illustrates a method of wetness detection using the reusable wetness detection sensor and an Internet of Things (IoT) device, according to some embodiments as disclosed herein; and
[00015] FIGS. 3A-3B illustrate examples of the reusable wetness detection sensor, according to some embodiments as disclosed herein.
DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS
[00016] The embodiments herein and the various features and advantageous details thereof are explained more fully with reference to the non-limiting embodiments that are illustrated in the accompanying drawings and detailed in the following description. Descriptions of well-known components and processing techniques are omitted so as to not unnecessarily obscure the embodiments herein. Also, the various embodiments described herein are not necessarily mutually exclusive, as some embodiments can be combined with one or more other embodiments to form new embodiments. The term “or” as used herein, refers to a non-exclusive or, unless otherwise indicated. The examples used herein are intended merely to facilitate an understanding of ways in which the embodiments herein can be practiced and to further enable those skilled in the art to practice the embodiments herein. Accordingly, the examples should not be construed as limiting the scope of the embodiments herein.
[00017] The accompanying drawings are used to help easily understand various technical features and it should be understood that the embodiments presented herein are not limited by the accompanying drawings. As such, the present disclosure should be construed to extend to any alterations, equivalents, and substitutes in addition to those which are particularly set out in the accompanying drawings. Although the terms first, second, etc. may be used herein to describe various elements, these elements should not be limited by these terms. These terms are generally only used to distinguish one element from another.
[00018] As mentioned, there remains a need for a reusable wetness detection sensor for detecting a wetness. The embodiments herein achieved this by stitching conductive threads into a fabric of the reusable wetness detection sensor. Unlike conventional wetness detection, the reusable wetness detection sensor is affordable and easy to manufacture. Referring now to the drawings, and more particularly to FIGS. 1 to 3B where similar reference characters denote corresponding features consistently throughout the figures, there are shown preferred embodiments.
[00019] FIG. 1 depicts a reusable wetness detection sensor 100, according to some embodiments as disclosed herein. The reusable wetness detection sensor 100 includes a fabric 102, and an Internet of Things device 106. The fabric 102 includes a plurality of conductive threads 104. The plurality of conductive threads 104 may include one or more Input/Output (IO) threads and one or more ground threads. In some embodiments, the fabric 102 may include maybe a cotton, a rexine, a rubber fabric, and the like. The plurality of conductive threads 104 are spread across the fabric 102 to detect a wetness due to water or any other liquids overflowed to the reusable wetness detection sensor 100. The plurality of conductive threads 104 are stitched or embedded on the fabric 102 in a pattern of an alternative of IO threads and ground threads. The IO threads and the ground threads are connected to a General-Purpose Input Output (GPIO) and a ground of the Internet of Things (IOT) device 106. The IO threads are pulled to high by an internal pull up resistor of the IOT device 106 and a value of IO port will be “1” when the reusable wetness detection sensor is dry. The value of the of IO port will be “0” when the reusable wetness detection sensor is wet. Sensor detects the wetness and transmits the data through wireless module to process the data.
[00020] In some embodiments, for example consider a person sleeping on a bed configured with the reusable wetness detection sensor 100, when the person urinates or when the person’s diaper get full, the urine starts flowing on to the bed and then to the reusable wetness detection sensor 100.Due to the flow of the urine through the sensor 100, a conductive path gets established between the IO threads and the ground threads of the reusable wetness detection sensor 100. The IO port of the IOT device 106 which is internally pulled to high by the internal resistor on the IOT device 106 will be pulled to ground and the value of the IO port changes to “0”. A change of state from “1” to “0” of the IO port is determined as wetness by the IOT device 106. In another example, consider a person sitting on a bed or any surface where the wetness detection sensor 100 is places and the person spills water or coffee or any other liquid is also detected by the sensor 100.
[00021] In some embodiments, the reusable wetness detection sensor 100 is foldable, washable, and reusable once dried. The reusable wetness detection sensor 100 may be placed under a bed sheet of a patient or an infant or any person who uses diapers. The reusable wetness detection sensor 100 detects the wetness due to a diaper overflow of infant or the person who uses the diapers. The reusable wetness detection sensor 100 can also detect moisture. The water or other liquids on a rexine reusable wetness detection sensor 100 can be wiped off and disinfected.
[00022] FIG. 2 illustrates a method 200 of wetness detection using the reusable wetness detection sensor 100 and an Internet of Things (IoT) device, according to some embodiments as disclosed herein. At step 202, the method 200 includes establishing, by the reusable wetness detection sensor 100, the conductive path between the IO threads and the ground threads when a water or any other liquids reaches the plurality of conductive threads 104. At step 204, the method 200 determining, by the IOT device 106, the wetness based on the established conductive path.
[00023] FIGS. 3A-3B illustrate examples of the reusable wetness detection sensor, according to some embodiments as disclosed herein. Refereeing to the FIG. 3A shows a first example of the reusable wetness detection sensor 100 stitched or embed on a cloth. Refereeing to the FIG. 3B shows a second example of the reusable wetness detection sensor 100 stitched or embed on a rexine.
[00024] The foregoing description of the specific embodiments will so fully reveal the general nature of the embodiments herein that others can, by applying current knowledge, readily modify and/or adapt for various applications such specific embodiments without departing from the generic concept, and, therefore, such adaptations and modifications should and are intended to be comprehended within the meaning and range of equivalents of the disclosed embodiments.
