Inspiration

How can we make refilling home containers more efficient and convenient?

What it does

A device and app that tells you exactly how full your containers are, in real time.

How we built it

We started with an ultrasonic distance sensor and used Arduino with WiFi to send that data to a backend server that we created using Node.js. Then we connected the backend to a React app to display the data.

Challenges we ran into

We initially ran into some problems with sending data from Arduino to the backend server as we didn't know exactly how to receive the exact data we wanted. We persevered and figured out the problem.

Accomplishments that we're proud of

We're proud of having a fully functional device and app.

What we learned

We learned more about connecting hardware with software for solving problems.

What's next for ReFill

The data we record can also be utilized to send messages when a container urgently needs refilling.
