Milk Monitoring System using IOT-Based Smart Sensors

The Milk is a widely consumed nutritional product, but its quality is often affected by contamination and harmful residues such as antibiotics and pesticides. Ensuring milk safety using traditional laboratory methods is time-consuming and not suitable for real-time monitoring. This project proposes a Milk Residue Limit Monitoring System using IoT and sensorbased technology for continuous quality assessment. The system utilizes sensors such as pH and temperature to monitor key parameters of milk. The collected data is processed using a microcontroller like ESP32 or Arduino and transmitted to a cloud platform for remote monitoring. The system analyzes the data by comparing it with predefined safe limits to detect contamination or spoilage. An alert mechanism is incorporated to notify users through buzzers and mobile notifications when abnormal conditions are detected. This approach reduces manual effort and enhances transparency in the dairy supply chain. The proposed system is cost-effective, reliable, and suitable for real-time applications. Overall, it ensures safe milk consumption and improves food safety standards.
