IoT-Nose an AI Powered Smart Fridge Spoilage Detection

Imagine opening your fridge and instantly knowing whether your food is still fresh – before the smell hits you! This AI-powered Smart Fridge Spoilage Detection System is a futuristic project that brings together IoT sensors, artificial intelligence, and mobile connectivity to transform everyday food storage into a cutting-edge innovation.

At its core, the project uses the Bosch BME688 sensor pod, which doesn’t just measure temperature, humidity, and air pressure, but also sniffs out complex volatile organic compounds (VOCs) like ethanol, hydrogen sulfide, ammonia, and amines – the real culprits behind food spoilage.

Unlike traditional solutions, this system learns each fridge’s unique “normal smell signature” and builds an AI profile over time. The machine learning model then predicts:

• ⚡ Early Spoilage Alerts – Detect changes long before food visibly spoils.

• 📲 Mobile Notifications – Sends freshness alerts and spoilage warnings right to your smartphone.

• 🕒 Remaining Freshness ETA – AI-driven prediction of how many hours/days are left before food goes bad.

This project isn’t just academic submission material – it’s also an industry-grade innovation that can be showcased in placements, internships, and startup pitches. With the BME688 sensor’s AI capabilities, students get hands-on exposure to real-world ML training, IoT communication, and smart home integration, making it a powerful addition to any engineering portfolio.
