7. Our product has been designed to tackle some of the UN sustainability goals. These are
a. Goal 6—Our product reduces water waste by using automated movement sensing and having timers in the background. This will allow users to shower responsibly and efficiently manage their water consumption.
b. Goal 3 – How the smart shower works will enable users to monitor water temperatures and create a secure bathing environment, which directly contributes to the overall health of the users. In ways such as health, avoiding dry skin, and safety, avoiding dehydration due to prolonged exposure to water.
c. Goal 12—efficient water consumption by having shower durations and raising awareness of it could lead to people changing and developing responsible habits for water consumption.
d. Goal 11 – By integrating our product into their lives, people can improve and sustain better living expenses and environments

Movement sensor – that will check if someone is in the shower or just standing there doing nothing. (Will turn the shower head if the person is standing still for too long.) placed around the tub.

Temperature sensor – monitor the temperature in the bathroom and warn the user if it passes a certain threshold. When it gets too hot or when it gets too cold or steamy. (sounds the alarm or lights the LED lights accordingly [red if too hot/ steamy, green if the temp is moderate, blue if the bath gets too cold or low temp).

LED lights – lights that are in the tub that light accordingly to the circumstance: 1. temp – red if too hot/ steamy, green if the temp is moderate, blue if the bath gets too cold or low temp.
2. timer – green will flash on and off is on when the time limit is not finished and red when the is less that 2 minutes left.

Timer – allows the user to set a time limit and this will close (turn off) the water after the time set has passed.

Sound – a Beeb sound that will warn or inform the user of varies things.

The development of our smart showerhead involved several key stages, beginning with the first stage, we finalized the list of hardware components needed for the product and a basic (first draft) of the 3d model to be used: Step 2: 3D Design and Framework. In this phase, we designed the physical shower shell using 3D modeling software. The framework served as a mini prototype, showing the intended structure and appearance of the final product. Materials like PETG (chosen for its water resistance) or wood were used to 3D print individual components, which were later assembled based on a drafted blueprint.
Step 3: Product Assembly involved integrating hardware into the framework. The microcontroller was installed first, acting as the central unit and connected to a power source via USB. One by one, the sensors were wired: motion, temperature and humidity, LEDs, and finally the water pump. Once assembled, the system was ready for programming.
In Step 4: Coding, we programmed each component using Arduino IDE. The motion sensor was coded to detect activity and reduce water flow when inactive. LEDs responded to water temperature (red for hot, blue for cold, green for optimal). The temperature and humidity sensor regulated temperature alerts, while the water pump maintained a fixed flow rate. The timer controlled the session duration, shutting off the pump when time was up. Finally, the sound module triggered alerts when needed.
Step 5: Testing and Adjusting focused on performance checks and refinements. We ran multiple tests, fine-tuning or replacing parts to improve reliability and function. To scale production, we plan to seek investment or supplier partnerships. With enough funding, we aim to release a simplified MVP version for early users, then progress toward a fully polished, market-ready model.
