Greenclean

Inspiration

I was showering one day and I had my eureka moment, I began to wonder how crazy it is that I can never know how much water I'm using. Though the recommended shower time is 8 minutes which uses approximately 65 liters of hot water, many of us tend to linger much longer wasting a lot of precious water.

What it does

First, there is a user interface that asks how many liters of water the user would like to use. After setting the amount, the LED display shows the amount of water used and the temperature of the water. Once the amount of water set has been used, a buzzer will go off to let the user know.

How we built it

I used an Arduino Uno R3 and hooked up two push buttons, a buzzer, an lcd display, waterflow sensor, and a temperature sensor. I had also 3D printed a model of a showerhead so that my circuit would seamlessly mix with my model.

Challenges we ran into

I ran into many challenges such as my model coming out wrong and needing some editing. The biggest one I had ran into is when I learned my temperature sensor is just stranded wires and I need to find a way to hook that into my circuit. This was my first time encountering such a problem so I was puzzled at first but with some research, I learned that I could just cut male jumper cables and twist it onto the wires for the temp sensor and use electrical tape to make it semi permanent.

Accomplishments that we're proud of

I'm really proud of the 3d model as it is something I came up with within a week and I managed to keep the measurements just right for my pieces to fit in.

What we learned

I learned many things in the course of making this project. I learned to make my own wires, how to use TinkerCad to 3d print models, and I learned how to use an LCD display.

What's next for Greenclean

I'd like to learn more about prototyping, mainly soldering, so I can get a cleaner and more ergonomic model of the shower head.
