🧊 Smart Food Inventory Tracker App — Product Demo
🎓 Built for COEN/ELEC 390 at Concordia University by Team 4

In this video, we showcase our Android-based Smart Food Inventory Tracker, designed to help users reduce food waste and improve food safety by monitoring both inventory and environmental conditions inside the fridge.

🚀 What the App Does:

Tracks fridge temperature, humidity, and gas levels (CO, LPG, NH₄) in real time
Notifies users when conditions are unsafe or when products are nearing expiry
Supports manual product entry and barcode scanning via OpenFoodFacts API
