Smart Sensors and IoT: A New Era in Supply Chain Visibility


In today’s fast-paced digital transformation world, supply chain visibility is more important than ever. Businesses need to be able to track their products and materials from the moment they are sourced to the moment they are delivered to customers. This can be a complex and challenging task, but the advent of Smart sensors and the Internet of Things (IoT) is making it easier than ever before. It involves capturing real-time data and gaining insights into the various stages of the supply chain, including procurement, production, transportation, and distribution.

Traditionally, supply chains have been fragmented and complex, making it difficult to track goods in real-time. Additionally, manual data collection and outdated technologies lead to data silos and limited visibility.

This is where technology comes into play. The advent of smart sensors and the Internet of Things (IoT) has revolutionized the way supply chains operate, offering unprecedented visibility into the movement and condition of goods. Let’s delve deeper into the world of smart sensors and IoT to understand how they enhance supply chain visibility.

Understanding Smart Sensors and IoT

Let’s understand the basics of smart sensors and IoT along with how sensors and IoT enhance supply chain visibility.

Smart Sensor: Smart sensors are advanced devices that capture data from the physical world and provide real-time insights. These sensors are equipped with built-in processors, memory, and communication capabilities, allowing them to collect and transmit data wirelessly. They are designed to be highly adaptable and can monitor various environmental conditions such as temperature, humidity, pressure, and location.

The applications of smart sensors are vast and span across different industries. In healthcare, they can monitor patients’ vital signs and detect anomalies. In agriculture, they can optimize irrigation and monitor soil conditions. However, their significance in supply chains cannot be overstated. By attaching these smart sensors to shipments, companies can track their location, monitor environmental conditions, and even detect any unexpected movements or tampering.

IoT: The Internet of Things (IoT) encompasses a network of physical devices, including vehicles, home appliances, and various items. These objects are embedded with electronics, software, sensors, actuators, and connectivity, facilitating their ability to connect and exchange data.

By leveraging IoT, companies can achieve real-time tracking and monitoring of goods throughout their journey. From the warehouse to the customer’s doorstep, every step can be monitored, ensuring timely and efficient delivery. IoT also enables the collection of massive amounts of data, which can be used for predictive analytics, demand forecasting, and optimization of supply chain processes.

How are smart sensors and IoT being used in supply chain visibility?

Smart sensors act as the eyes and ears of the supply chain, capturing data at various touchpoints. IoT serves as the backbone, connecting these sensors and facilitating the seamless exchange of data.

Together, smart sensors and IoT technologies complement each other to enhance supply chain visibility. Smart sensors provide the granular data required for real-time tracking, while IoT enables the transmission, aggregation, and analysis of this data. This convergence eliminates information gaps, enabling stakeholders to make informed decisions and take immediate action when deviations from the plan occur.

In the logistics sector, containers equipped with smart sensors can provide real-time information on location, temperature, and humidity. This allows companies to monitor the conditions of perishable goods during transportation and take proactive measures to mitigate risk.

In retail, IoT-enabled shelves equipped with smart sensors can track inventory levels and send alerts when products need to be restocked. This ensures better inventory management and reduces out-of-stock situations.

There are many ways that smart sensors and IoT are being used to improve supply chain visibility, which are Tracking shipments, Monitoring conditions, Optimizing routes, and Predicting demand.

Applications of Smart Sensors and IoT in Supply Chain Visibility

Track and Trace Capabilities

Track and trace solutions allow companies to track the movement of goods in real-time, from the point of origin to the final destination. By attaching smart sensors to shipments, companies can collect data on location, temperature, humidity, and other environmental conditions.

With this real-time visibility, companies can proactively identify delays, optimize routes, and take necessary actions to prevent disruptions.

Like in the pharmaceutical industry, the ability to track and trace medicine shipments ensures product integrity and compliance with regulatory requirements.

Case studies highlight the benefits of track and trace applications. One such example is Maersk, the world’s largest container shipping company. Maersk implemented an IoT-based track-and-trace solution that provides real-time visibility into the location and condition of its containers. This enables Maersk to optimize its operations, reduce costs, and deliver goods more efficiently.

Predictive Analytics for Demand Forecasting

Smart sensors and IoT play a crucial role in collecting data for demand forecasting. By continuously monitoring various environmental conditions, including temperature, humidity, and demand signals, companies can gather valuable insights into consumer behavior and market trends. This data can then be analyzed using predictive analytics algorithms to forecast demand accurately.

Companies can optimize inventory levels, adjust production volumes, and ensure timely deliveries. For instance, a beverage manufacturer can leverage predictive analytics to its production schedule based on weather patterns, ensuring that the right products are available in the right locations at the right time.

The global logistics company DHL introduced predictive analytics to optimize its demand forecasting process. By analyzing historical data, weather patterns, and sales trends, DHL improved its demand accuracy by 15% and reduced stock-outs by 50%.

Condition Monitoring and Quality Control

Real-time condition monitoring is vital for ensuring product quality, minimizing losses, and reducing risks in supply chains. Smart sensors enable continuous monitoring of environmental conditions. This allows companies to detect potential issues, such as deviations in storage temperature or equipment malfunctions before they escalate into major problems.

By continuously monitoring conditions, stakeholders can ensure that goods are stored under optimal conditions, preventing spoilage or damage.

Several case studies demonstrate the importance of condition monitoring and quality control in supply chain visibility. Nestle, a leading food and beverage company, implemented a smart sensor-based monitoring system for its refrigerated transport vehicles. This system continuously monitors temperature, humidity, and other environmental factors, ensuring compliance with quality standards and reducing the risk of product spoilage.

Overcoming Challenges

There are a few challenges associated with using smart sensors and IoT in supply chain visibility. Among these, key issues include:

Cost: Smart sensors and IoT can be expensive to implement and maintain.

Security: Smart sensors and IoT can be vulnerable to security breaches.

Data integration: Integrating data from smart sensors and IoT with existing business systems can be a challenge.

Despite these challenges, the benefits of using smart sensors and IoT in supply chain visibility are clear. Businesses that can overcome these challenges will be well-positioned to succeed in the increasingly competitive global economy.


The integration of smart sensors and IoT in the supply chain is not just a trend, but a necessity for businesses to stay competitive in the digital age. Companies should consider investing in these technologies to increase value capture through their supply chains after carefully prioritizing their business objectives and defining their use cases. The future of supply chain visibility is here, and it is smart, efficient, and connected.
