Inspiration
Cities waste millions every year sending garbage trucks on fixed schedules — emptying half-full bins while others overflow onto the streets. We wanted to fix that with a simple, scalable IoT solution.
What it does
FillAlert monitors garbage bins in real time using an ultrasonic sensor mounted inside the bin. It calculates the fill level as a percentage and pushes that data to a live dashboard showing every bin on a map, color coded by urgency. When a bin hits 80% capacity, it automatically sends an SMS alert to the waste collection depot so trucks are dispatched only where they're actually needed.
How we built it
Challenges we ran into
Blocking Systems, we fixed this by implementing the ESP32's dual core system and spead the tasks to those cores evenly
Accomplishments that we're proud of
We are proud of our email implementation, this sends to your gmail once the trash can is full.
