Cold Storage Monitoring System

Cold storage facilities play a critical role in preserving temperature-sensitive products such as food, pharmaceuticals, and biological materials. Even minor temperature deviations can lead to product spoilage, regulatory non-compliance, and financial loss.

To address these challenges, an IoT-based Cold Storage Monitoring System was implemented to ensure continuous environmental control, real-time monitoring, and automated alerting.

Cold Storage Monitoring

Problem Statement

The client faced multiple operational challenges in their cold storage facility:

  • Manual temperature logging leading to human errors.
