Project Idea
Design a smart cold chain monitoring system that continuously tracks temperature, humidity, and location of perishable goods during transportation and storage. Using IoT sensors and cloud integration, it ensures product quality, compliance with standards, and timely alerts for deviations.
Project Description
The IoT-Based Cold Chain Monitoring System uses temperature and humidity sensors placed inside storage units or refrigerated vehicles to monitor environmental conditions in real time. Alerts are triggered when temperature or humidity goes out of the safe range, allowing corrective action to be taken quickly. Historical data logs support compliance with regulatory requirements and help in analyzing trends for process improvement.
