1. Executive Summary
Usage of disposable diapers has been increased significantly in last two decades.
Wetness in Diaper can cause dermatitis and skin rashes. In order to avoid that, diaper
need to be removed as soon as it become wet. This project aims to design a moisture
detection system for diapers. The system notifies the caregiver or parents whenever it
is required to change the diapers. The system consists of three main parts: disposable
sensor, rechargeable moisture detection system with Bluetooth transmitter and a
smartphone application.
The project starts with researching available solutions to the problem and the
requirements needed for the system to start out from the crowd. The company
“smartCare” designs the system, analyse the design to ensure that it is reliable, small
and affordable for public. Then to develop a prototype and test it. After deciding the
final product, the company then starts to commercialize it.
A detailed plan for work is created using Work Breakdown Structure (WBS). The cost
estimation includes estimate cost of human resource, research, design, marketing and
for monitoring and control. A milestone list is created to keep track of main objectives
and results produced by the project. Gantt chart and network diagrams are used to
generate a proper implementation strategy. A stakeholder analysis has been done to
identify stakeholders and to analyse their needs.

2. Introduction
Babies and people who suffer from dementia and intellectual disability are not able to
handle their urination themselves. In such cases, detection for wet diaper is essential.
Infrequently changed wet diapers may create rashes on the skin. Generally, someone
needs to check whether the diaper is wet or dry. But there is a need for moisture
detection system to alert the guardian or caregiver when it is required to change
diapers.
The aim of this project is to design and market a low-cost disposable moisture detection
device that can be used along with normal diapers. The whole product consists of four
parts; Wet detection sensor, microcontroller, Bluetooth transmitter and a smartphone
app. The sensor regularly detects the status of moisture and send signal to the
microcontroller when the diaper is wet. After that, the signal is transmitted to Bluetooth
paired device. The smartphone app receives the signal and notifies the user.
One of the main advantages of this product is its cost. The product is less expensive than
its other similar products available in the market. Each disposable wearable sensor may
cost between $0.2 and $0.4. The detection device is reusable which may cost around
$20 to $30. The smartphone app is available in google play store and apple app store

4. Purpose of Project and Problem Statement
Wet diapers can cause rashes and dermatitis. To prevent this, doctors prescribe diaper
creams and gel which has side effects. It is inconvenient for the caregiver to check for
wet diapers frequently. In this condition, there is a need for smart diaper moisture
detection system.
The team members are working effectively to get parts done by given deadline. One
team is currently developing the prototype. Prototype is tested once it is developed.
Another team is currently working on smartphone application, which is expected as per
the schedule.
The project is sponsored by the company itself. The expense for this project is allocated
from the revenue of the company.
5. Critical Assumptions and Constraints
The team considered various approaches for the effectiveness of our project. Out of all
the possible strategies to be consider, the manufacturing process, environment factor
and service are concluded have the largest impact for the proper functionality of the
project.
Manufacturing: It is significant to consider the capabilities and constraints of the
manufacturing operations. Things like internal production facilities and assembling of
product, the capacities of the existing technologies to provide an outcome required for
our product should be considered.

Environment: We have the challenge to make the smartCare product environmentally
sustainable. The stated goal of product is that it will be disposable and is zero percentage
harmful for the environment.
Service: Essentially, the product should meet the expectation of customer service and
the service revenue. Goals for serviceability of smartCare includes the less installation
time of product and the quality and comfort during use.
