Introduction
This project integrates IoT sensors with AI-driven analysis to monitor and predict chemical properties in real time. Using components like Arduino Uno, pH sensor, and color sensor, it primarily focuses on milk quality assessment. A Python-based machine learning model (Random Forest) analyzes the sensor data to detect adulteration and classify milk as Fresh, Acceptable, or Spoiled, enhancing accuracy, reducing human effort, and increasing reliability.
B. Objectives
Real-time chemical monitoring and prediction.
Automation using IoT and AI technologies.
Detection of chemical anomalies with machine learning.
C. Literature Survey Highlights
Random Forest model shows 96% accuracy in milk quality prediction.
Deep learning autoencoders used for extracting sensory data features.
Quality is determined by temperature, pH, and color:
Example (Pasteurized Milk):
At 4–7°C, pH 6.6, RGB 255 → Excellent
At 30–44°C, pH 6.3, RGB 180 → Bad
Conclusion
The integration of an Arduino UNO with a TCS3200 color sensor provides an effective and cost-efficient method for monitoring milk quality based on color changes. By capturing real-time RGB values from the milksample, thesystem can detect the degree of spoilage, offering a non- invasive solution for quality assessment. The collected data can be further processed using machine learning algorithms, such as Random Forest, to accurately classify milk as fresh, acceptable, or spoiled. This system offers a promising approach for ensuring milk safety and quality in dairy production, with the potential for integration into automated milk processing environments, improving both efficiency and consumer confidence in milk products.
In the future, the system can be integrated into automated dairy farms and processing plants for continuous, real-time monitoring of milk quality. By using sensors at multiple stages of milk production, the system can help track the quality from the farm to the consumer, ensuring optimal freshness and safety throughout the supply chain.
