IoT in Warehouse Management: Use Cases and Best Practices

7 IoT Applications in Warehouse Management

Now that we’ve explored the key benefits of integrating IoT in custom warehouse management systems, it’s worth exploring specific applications where this technology can make a significant impact.

1. Inventory optimization 

Always know what you have on hand! IoT solutions, such as sensors and RFID tags on shelves and pallets, track stock levels in real time, allowing for precise details on location and status of goods. This data feeds into an inventory management system to provide accurate insights into what’s on hand, where it is, and when it needs to be replenished. Automated replenishment systems monitor stock levels and trigger reorders when supplies run low. 

For instance, with the help of machine learning algorithms, the system first produces a broad forecast of the anticipated quantity of each item needed over a given timeframe. This forecast is then refined by applying specified parameters, such as the minimum required inventory levels, supplier delivery lead times, and minimum order quantities. Such info helps to optimize space utilization and makes for faster picking and minimized stockouts.

2. Asset management 

IoT technology enables you to effectively manage business assets within the warehouse environment by tracking the location, condition, and status of equipment and resources in real time with precision. 

Sensors, RFID tags, or GPS trackers are attached to valuable equipment such as forklifts, pallet jacks, etc. to keep tabs on every asset within the facility, providing real-time data on inventory levels, product locations, and environmental conditions, as well as sending security alerts to warehouse managers. This helps to prevent loss or theft of valuable assets.

3. Automation of processes 

IoT-enabled devices such as automated guided vehicles and robotic arms can automate tasks such as order picking, packing, and sorting, leading to faster fulfillment cycles and improved productivity.

AGVs equipped with sensors and GPS can navigate warehouse aisles autonomously, retrieving items from shelves and delivering them to packing stations. This eliminates the need for manual forklift operations, reducing the risk of accidents and freeing up workers to focus on higher-value tasks.

4. Transportation

IoT applications facilitate efficient transportation management within the warehouse by tracking the movement of goods, optimizing picking and delivery routes, and monitoring vehicle performance. Sensors on vehicles and trailers, in turn, track location, speed, and cargo conditions.

For instance, as pallets or boxes are loaded onto a truck, RFID readers detect the items and automatically update the transportation management system with the manifest. This eliminates manual data entry and ensures accuracy. Upon arrival at the destination, the same process occurs in reverse, streamlining the unloading process.

In this way, integration of IoT sensors in vehicles and shipping containers enables you to improve shipment tracking, reduce transit times, and enhance overall logistics coordination.

5. Wearable devices 

Wearable IoT devices such as smart glasses, wristbands, and sensors provide warehouse personnel with hands-free access to critical information, instructions, and notifications while performing tasks. For example, workers can wear smartwatches or other wearable devices that track their location, vital signs, and work patterns.

One shining example is DHL’s use of smart glasses in their warehouses. These devices provide workers with step-by-step instructions for order picking, highlighting the correct bin locations and quantities. This has led to a 25% productivity increase in picking  processes. The glasses also allow for remote assistance, with supervisors able to annotate the worker’s view to provide guidance.

6. Storage racks moved by robots

Automated storage and retrieval systems (AS/RS) driven by IoT sensors can automate the movement and organization of storage racks within the warehouse, optimizing space utilization and enhancing inventory management. These robots are typically equipped with various sensors, RFID readers, and navigation systems to move safely and accurately within the warehouse environment.

Intelligent algorithms then direct autonomous mobile robots to retrieve, relocate, and reorganize the racks based on factors like item popularity, expiration dates, and storage density. For example, fast-moving products can be placed in the most accessible aisles, while slower-moving items are stored in higher-density configurations. 

By automating these storage and retrieval tasks, AS/RS systems eliminate the need for manual forklift operations, reducing the risk of accidents and injuries.

7. Warehouse maintenance

IoT applications support proactive maintenance of warehouse facilities and equipment by monitoring performance metrics, detecting anomalies, and predicting maintenance needs. Sensors monitor equipment performance, temperature, and vibration levels.

As an illustration, the leak detection system developed by HQSoftware incorporates sensors that allow users to keep an eye on water pipes for any sign of leakage issues.

A sensor device designed as a flat plate that is placed underneath pipes with a high risk of leaking, like those found under sinks, washing machines, and ice makers. It utilizes several detection points to provide accurate leak monitoring. 

So, IoT-enabled predictive maintenance systems help prevent equipment breakdowns, minimize downtime, and extend the lifespan of warehouse assets.

IoT devices for warehouse management

Imagine a warehouse where every shelf knows its inventory, every forklift tracks its location, and every package’s journey is meticulously documented. This is the reality being built by companies leveraging the power of IoT. Some of the most commonly used IoT devices for warehouse management include:

• GPS trackers;
• RFID tags;
• Smart sensors;
• HVAC systems;
• AI cameras. 

GPS trackers

With vast spaces and countless inventory items moving through warehouses every day, keeping track of everything can quickly become an onerous task. This is where GPS technology can play a valuable role, by providing pinpoint location data that can be used to enhance various warehouse workflows. 

For example, attaching trackers to storage racks, forklifts, scooters and other equipment allows their movement throughout the facility to be carefully monitored at any given time, ensuring efficient utilization of expensive machinery.

GPS is also useful for tracking high-value or temperature-sensitive shipments requiring extra care. Placing a tracker inside a crate of fragile electronics or on a pallet of frozen food helps verify its location every step of the way. If any irregularities occur, such as prolonged stationary periods or unauthorized zone entries, alerts can be triggered immediately.

RFID tags

Reliably keeping tabs on thousands of inventory items spread across massive warehouse facilities can be a challenging task. To overcome this issue, RFID tags are programmed with unique identifiers and attached to items like pallets, cases, or individual products, enabling accurate asset tracking in real-time.

Fixed RFID readers installed throughout the warehouse seamlessly capture tag signals as they pass within range, recording location and time data. This feeds into a WMS to continuously update each item’s location and support automated processes.

Compared to barcode scanning, which requires line of sight, RFID allows high-volume, contactless tracking of items on the move. As pallets are transported between zones on conveyor belts or vehicles, their progress is automatically logged without slowing workflows. 

Smart sensors

Sensors, the eyes and ears of the warehouse, are the tiny devices that collect and transmit data about warehouse surroundings. These sensors can be attached to everything from pallets and shelves to forklifts and even individual products. They monitor location, movement, temperature, humidity, and levels in storage areas, ensuring that perishable goods are kept in optimal conditions. Smart sensors can be categorized as:

• Environmental sensors: when attached to freezers, coolers, etc., these sound alerts if readings dip outside preset ranges, drawing immediate attention before product is damaged;
• Vibration sensors: attached to heavy machinery, these can detect anomalies that may indicate future breakdowns; 
• Level sensors: placed in bins, they can notify when inventory gets too low, triggering replenishment before an out-of-stock leads to shipping delays; 
• Motion sensors: these can provide insights into workspace utilization, automatically adjusting lighting, cooling, and other utilities based on detected movement in different zones. This saves huge amounts of energy that would be wasted by continuously running empty areas at full power.

HVAC systems

When handling temperature-sensitive goods worth millions, precise environmental control is mission-critical. Heating, ventilation, and air conditioning systems (HVAC) play this vital role, and IoT is empowering them to operate with unprecedented efficiency.

Traditional HVAC units run on fixed schedules, oblivious to real-time needs that vary daily. Now sensors provide insights to optimize settings continuously. Thermostats leverage IoT to monitor numerous zones independently, adjusting cooling/heating based on actual occupied spaces.

This avoids wasting energy by conditioning empty areas unnecessarily. Sensors also detect leaks, humidity levels, air velocity and more to flag maintenance needs before critical failures occur. Predictive analytics draw patterns to avoid temperature fluctuations that cause condensation or product spoilage.

AI cameras

As warehouses scale to gargantuan sizes, monitoring vast open floors and tall shelving areas becomes nearly impossible without extra help. Strategically placed IP cameras equipped with advanced computer vision can identify issues across the facility without human oversight. Artificial algorithms detect anomalous behaviors such as tailgating or congregation that impede workflow efficiency. They also flag safety concerns such as protection protocol violations, chemical spills or potential equipment malfunctions.

But these smart cameras do much more than just spot problems – their AI capabilities enable automation. Object detection identifies products, shelving locations and other assets to provide real-time floor maps. This supports automated inventory management, routing of self-driving vehicles such as carts and drones, and updated space utilization analytics.
