Hydro Homie

Co-Creator | 2021

Overview

 The first water bottle to make hydration tangible and quantifiable.
 

​

Demo

The bottle

I, along with my partner Krishnan Kumar, created the Hydro Homie, a smart water bottle with WiFi connectivity. Our bottle is able to measure both the pH and turbidity (cloudiness) of the water inside the bottle while calculating how hydrated the user is based on their exhaled breath. The bottle can also compare the turbidity of the water of the nearest water source to the water inside the bottle. 

​

The sensors included in this project include:

  • pH sensor

  • Total Dissolved Solids sensor

  • Humidity and temperature sensor

​

The project won Best Project in EECSE 4764: IoT - Intelligent and Connected Systems

Hydro Homie

The App

Hydro_Homi_Screens.png

The app we developed for the Hydro Homie was done using Kivy, a Python library for rapid application development. The app has two screens: a screen that relays water information and a map screen.

 

On the water screen (left), the app has buttons for hydration level, turbidity levels (how cloudy the water is) of the bottle’s water and the water of the surrounding area, the pH of the bottle water, and the chlorine of the water in the surrounding area. The app connects to the Huzzah board via tunneling and gets information on the water in the bottle through the various sensors. The app also can be controlled via voice commands.

​

The map screen (right) shows your current location and the location of the nearest water fountains. When clicking on a fountain, the water quality information for the fountain appears. The APIs that we used for the map were the IP Geolocation API, NYC Parks Drinking Fountains Database from NYC Open Data and Drinking Water Quality Distribution Monitoring Database from NYC OpenData. The NYC Parks Drinking Fountains Database gave us the geolocation of the water fountains and the Drinking Water Quality Distribution Monitoring Database from NYC OpenData gave the water quality information and a geolocation of a testing site. We attributed the information from the nearest water quality testing site to the nearest fountain to that site.
