Inspiration

We wanted to use hardware instead of only software for the app. So we decided to incorporate unseen factors like air quality and temperature to reinforce accuracy.

What it does

As aforementioned, we take in unnoticed factors and make them noticed. By using an ESP32 module and a BME688 module, we monitor air quality and temperature, accounting for these factors, along with actual user input, to further enhance accuracy.

How we built it

Software: We mostly vibe coded the entire apps (Claude), one for the website and one for the app. The app has more features as it directly connects to the ESP32 using wifi, while the website has limited features and encourages people to use the mobile version. We used Google Firebase Console for a database and Vercel to deploy it
Hardware: (ONLY FOR MOBILE APP) We used a Bambu Lab 3D printer to hold the case of our main hardware, the ESP32-WROOM-32D and the Adafruit BME688, which detect the air quality and temperature. The ESP32 connects to the WiFi from your phone, which then shows accurate readings.

We used node.js for Firebase:

npm install firebase

and set it up

import { FIREBASE_CONFIG } from './firebase-config.js';

and deplyment for vercel

{
  "version": 2,
  "installCommand": "npm install",
  "builds": [
    { "src": "api/index.js", "use": "@vercel/node" }
  ],
  "routes": [
    { "src": "/(.*)", "dest": "api/index.js" }
  ]
}

and created a ve

Challenges we ran into

There were many challenges we faced during the hackathon:

Managing and working with it
Deploying the web build on Vercel
Getting the right unit of readings from the BME688
Keeping the 3D printer on when there were people accidentally knocking the extention cord off
Working with limited Claude tokens

Accomplishments that we're proud of

There were also many things to be proud of

Fixing firebase and vercel
3D prints working on the first try
Getting accurate results from the modules: (The BME measures in Celsius with a \(\pm 0.5^{\circ}\) range. So we needed to convert that to Farenheight with \(\frac{9}{5}C^{\circ} + 32\)

What we learned

We mostly got to know each other since we never worked with each other in a hackathon before, and we also learned how to integrate hardware into software, which also demonstrates to us the many applications of hardware in everyday life.

What's next for RestCue

We might enhance the website version and make the app more accessible (i.e. Android, other devices) and improving the hardware design, but that is what we can see so far.
