Ideation

<aside> <img src="/icons/water_blue.svg" alt="/icons/water_blue.svg" width="40px" /> Overall goal was to have a project with both a software and hardware side while keeping user needs in mind

</aside>

<aside> <img src="/icons/water_blue.svg" alt="/icons/water_blue.svg" width="40px" /> Idea was chosen by assessing feasibility (economic and time), user/market needs and individual goal achievement

Prototyping

<aside> <img src="/icons/water_blue.svg" alt="/icons/water_blue.svg" width="40px" /> Original plan was to use an ultrasonic sensor to measure the distance from the lid to the water and output to an application server

• Issues: the only cost effective waterproof ultrasonic sensor would measure a minimum distance of 20 cm (average water bottles when empty are around 20cm); a user friendly and useful app would take time and money far out of scope for this project timeline and budget </aside>

Final Product

<aside> <img src="/icons/water_blue.svg" alt="/icons/water_blue.svg" width="40px" /> Using an etape water sensor that outputs amount of water in the bottle to a local webpage via bluetooth

• The etape sensor works by utilizing the hydrostatic pressure of the water in the bottle to output as a resistance which is then calculated as a water height
• The local webpage outputs values collected from the sensor which has been integrated through a series of Python and Javascript </aside>

<aside> <img src="/icons/water_blue.svg" alt="/icons/water_blue.svg" width="40px" /> AQUA SENSE– we created a Nalgene water bottle cap that tracks water intake and outputs to a webpage which allows the user to view past water intake habits; the goals of the project were to make a cheaper and more user friendly water tracker with remote monitoring support

The main technical focus of the project was integrating sensor readings into a local webpage via a bluetooth server
