One-Tank — Propane Monitoring App

One-Tank is a propane tank monitoring app that enables real-time tracking of tank levels, temperature, and environmental data, with intelligent alerts and notifications when readings cross meaningful thresholds. A Flutter front end talks to an ASP.NET REST backend feeding live sensor data.

Running out of propane unexpectedly — or missing a temperature anomaly — is costly and inconvenient. Owners needed a way to see tank status at a glance from their phone and be warned before a problem became an emergency, using live data from physical sensors.

One-Tank streams sensor readings through an ASP.NET REST API into a Flutter app, rendering custom charts of tank level, temperature, and environmental data in real time. An intelligent alert system pushes notifications when readings cross configured thresholds, and Riverpod keeps the live state consistent across the UI.

I built the Flutter app — consuming the ASP.NET REST API, rendering real-time charts of sensor data, managing live state with Riverpod, and implementing the threshold-based alert and notification system.
