IoT Smart Milk Freshness Detection System

Milk is one of the most consumed products worldwide, but it spoils quickly due to temperature changes, contamination, and poor storage. This project brings IoT + AI intelligence into your kitchen or dairy setup! Using a pH sensor and temperature sensor, the system continuously monitors milk quality in real time. If the pH drops (indicating souring) or the temperature crosses unsafe limits, it instantly sends alerts to your mobile app dashboard.

Students get a fully built solution – no stress, no confusion. Everything from hardware setup to app-based monitoring is included. This project doesn’t just fit academic submissions; it also boosts placements and resumes because it deals with real-world food safety, IoT systems, and smart monitoring applications.
