Why Reliable Cold Chain Monitoring Matters

banner
  • Temperature failures in the cold chain lead to far more than “out-of-range” alerts. They directly impact food safety, pharmaceutical efficacy, regulatory compliance, brand reputation, and so on.

Where Cold Chain Monitoring Is Critical

  • Food Industry: Ensures safety for easily spoiled items like fresh produce, seafood, and frozen food during transport and storage.
  • Pharmaceuticals & Vaccines: Vital for preserving the efficacy of vaccines and medicines. Small temperature shifts can make them ineffective or dangerous.
  • Medical and Biotech: Life-saving products like blood and gene therapies need strict temperature control to maintain quality.

Risks and Losses Due to Cold Chain Failure

  • Product Spoilage: Temperature fluctuations can cause perishable goods to spoil, making them unsafe for consumption or use.
  • Regulatory Penalties: Non-compliance with standards (e.g., FDA, GMP) due to poor temperature monitoring can lead to fines.
  • Financial Losses: Includes goods loss, transportation costs, and potential compensation claims.
  • Brand Damage: Cold chain failures can harm customer and partner trust, affecting long-term reputation.
  • Blocked Business Opportunities: Non-compliance can prevent entry into projects or tenders from the start.

How IoT Enhances Cold Chain Reliability and Transparency

  • Monitor in Time: IoT cold chain temperature monitoring sensors send instant alerts if any parameter deviates, enabling prompt corrective action to prevent product loss.
  • End-to-End Visibility & Transparency: Cold chain devices track temperature and log data, ensuring compliance and providing transparency to customers and regulators.
  • Preventive Maintenance: IoT sensors monitor temperature to detect potential refrigeration issues, alerting when maintenance is needed.

  • In the warehousing stage, maintaining the correct temperature and humidity is crucial, especially for temperature-sensitive products like food and vaccines. Temperature fluctuations can cause spoilage or reduce the effectiveness of products, making precise environmental control essential.

Temperature & Humidity Monitoring

Products like vaccines, biologics, and medicines need constant temperature and humidity control. Even small changes can reduce their shelf life or effectiveness. Real-time tracking helps keep them in the best condition.

Optimizing Cold Storage Conditions

Cold storage facilities typically have different temperature requirements for different types of storage. With the right cold storage temperature monitoring system, each area can be precisely controlled to meet the specific needs of the products stored within.

Ensuring Inventory Accuracy

Real-time environmental monitoring reduces human errors from manual checks. This makes operations more efficient and helps prevent product loss caused by unnoticed temperature changes.

  • The cold chain transportation stage is where goods are in transit—vulnerable to temperature breaches during movement. Ensuring that temperature-sensitive products are maintained during transportation is essential to prevent spoilage or damage. Additionally, stable data communication via 4G is crucial for continuous remote monitoring, allowing prompt corrective actions when deviations occur.

Temperature Control During Transit

Monitoring ensures refrigerated trucks, containers, and railways maintain proper conditions, preserving product quality during the journey.

Traceability of Shipments

A full temperature record for each shipment is important for quality checks and regulatory compliance. This traceable history helps avoid disputes, lowers risks, and strengthens trust in your logistics operations.

Unexpected Door Opening Detection

With its built-in light sensor, TS60x can detect when a truck or container is opened unexpectedly. This helps identify potential risks such as tampering or unsafe handling during transit.

Abnormal Movement Monitoring

The tilt sensor of TS60x alerts you when goods are tilted, dropped, or exposed to strong impact. This early warning helps protect high-value items and reduces disputes over damage.

Visibility of Cargo Location

TS60x can report location through cell-based positioning, giving you visibility into each shipment's route. This supports better tracking, smoother coordination, and timely preparation at the destination.

  • Once products reach the retail environment, hospitality, healthcare, or other end-user locations, ensuring they are stored correctly on shelves or in refrigerators is essential to preserve their freshness and quality using continuous temperature monitoring devices.

Refrigerator & Freezer Monitoring

Real-time monitoring keeps food and beverages at the right temperature, reducing spoilage and waste.

Reducing Manual Inspections

By automating temperature monitoring in-store, businesses reduce the need for frequent manual checks, freeing up staff time for other tasks. This improves operational efficiency and ensures that products are always stored under optimal conditions without delays.

You May Want to Know

What is cold chain monitoring?

Cold chain monitoring involves the continuous tracking of temperature-sensitive products throughout the entire supply chain, ensuring they remain within the required temperature ranges during storage, transportation, and handling. This process is crucial for industries such as food, pharmaceuticals, and medical products. Cold chain solutions offer real-time insights into product conditions, reducing the risk of spoilage or non-compliance.

What are the business benefits of cold chain monitoring?

The business benefits of cold chain monitoring include reduced waste, compliance with industry regulations, and increased operational efficiency. By implementing an IoT cold chain solution, businesses can track products in real-time, ensuring that temperature-sensitive goods, such as pharmaceuticals or fresh produce, are maintained in optimal conditions throughout the supply chain. This enhances customer trust, improves compliance, and minimizes financial losses from temperature breaches.

Which sensors are needed beyond temperature?

While temperature is the primary focus, cold chain monitoring solutions often require additional sensors for tracking humidity, light, and location. These sensors provide a complete picture of the environment in which the products are stored and transported, ensuring comprehensive monitoring. For example, in the pharmaceutical industry, monitoring both temperature and humidity is essential to maintain the effectiveness of sensitive drugs and vaccines.

What happens if there is a temperature deviation during transit or storage?

If a temperature deviation occurs, Milesight sensors send real-time alerts via LoRaWAN® or 4G LTE Cat 1 to notify you immediately. This enables you to take corrective action promptly, whether it's adjusting storage conditions, rerouting shipments, or addressing equipment failures. By using these communication technologies, you can ensure timely intervention, minimizing the risk of spoilage or damage to sensitive goods, and maintaining the integrity of your cold chain.

Are the sensors easy to install and maintain?

Yes, Milesight's cold chain monitoring devices are designed for easy installation and maintenance. They are user-friendly and can be installed with minimal effort using a variety of methods, including adhesive, magnetic mounts, screws, or cable ties, depending on your setup.
