As smart sensors are placed in billions of connected devices around the world, new IoT applications are generating massive streams of data that enable a world of opportunities.

Consider the rise of smartwatches that allow people to track their fitness, monitor their sleeping patterns, measure their heart rate, and more. Think of a future where self-driving cars are able to collect, process, and store driving data at the edge to make road travel safer and more enjoyable.

As mobility and ways of working continues to be redefined, Khwaja Saifuddin, senior sales director, Middle East, Western Digital, highlights the top nine use cases of the IoT technologies.

  1. Autonomous and connected vehicles

Down the road, vehicles might be able to reach Level 5 autonomy and drive themselves fully without human intervention. Today, however, car makers and automotive startups are working on getting level 2, 3, and 4 self-driving technology right. Cameras, radar, LIDAR and a host of other onboard sensors are being used to capture information about road conditions, inform appropriate driving actions, and potentially prevent accidents. To make this happen, nearly 1 terabyte of data will be stored onboard in the near-term, and this amount could balloon to 2+ terabytes in the next decade.

Yet, there’s more to the cars of tomorrow than just autonomous driving. Thanks to the Internet of Things, cars can communicate with each other, the road infrastructure, and, perhaps someday, even pedestrians by using “vehicle-to-everything” or “V2X” technology. Fleets of autonomous vehicles could be managed through this type of communication, making travel faster and safer. Onboard the car, IoT-enabled devices could improve the engine diagnostics, GPS data, and infotainment system.

  1. Smart security for businesses and homes

Historically, security systems often simply used a low-resolution camera to passively capture video. This trend held whether at private residences or commercial properties. Now, smart security systems are being purpose-built to capture, store, and analyse continuous video streams. On top of the 4K video captured by high-resolution cameras, these systems can use an analytics layer with machine learning software to carry out pattern recognition and motion detection. For public transportation providers and venue managers, these real-time insights play a meaningful role in public safety – thanks to robust storage and compute at the device-level.

  1. Connecting your home to the Internet (of Things)

What if your home could be mostly automated? That’s the direction that connected home technology is headed in this IoT use case. Smart speakers function like a central command, enabling your household electronics to perform a variety of voice-activated functions. You could, for example, instruct your TV to stream the latest episode of your favorite show while dimming the living room lights and setting the thermostat to a cozy temperature. This approach stretches even further by integrating refrigerators, washers, dryers, and more. The goal is to provide control for most or all of a home’s systems – including energy, climate, entertainment, appliances, and home security – through a connected network of devices, sensors, tools and platforms.

  1. Smartwatches, fitness trackers, and other wearables

Thanks to an influx of new personal devices, the wearables market is thriving. In fact, a recent report predicts that this industry will cross over $27 billion and 233 million units sold annually by the year 2022. This global adoption is due in large part to smartwatches, which are expected to make up over half of all wearables sold in the coming years. Consumers are looking for seamless connection and interaction between their smartphones and smartwatches to track, manage, and secure their data — especially sensitive health data. At the same time, industry analysts are forecasting flat-to-declining sales for fitness trackers – possibly due to a perceived lack of features and inability to sync with existing smartphones.

But, technological innovation won’t just come on the wrist. A new subcategory known as “hearables” could disrupt the wearables industry, using voice-activated, connected headphones and earphones. With more headset makers ditching the headphone jack, these types of devices are expected to become commonplace in the future. Another opportunity is in portable medical devices that monitor blood pressure and heart rate, as well as alert ambulance dispatchers during a medical emergency.

  1. Machine-to-machine (M2M) connected devices

Today’s factories are using IoT-enabled machines to work smarter, not harder. By equipping machines with sensors, factory managers can more accurately map machine workloads, inputs, and outputs. They can also more closely track machine wear-and-tear, which leads to maintenance that is predictive rather than reactive and improves lifespan. With these features, factories are increasingly becoming automated, thanks to the wave of Industry 4.0. M2M devices use embedded and removable flash solutions to aggregate data into a single stream at the edge. This gateway is used to monitor and react to changing conditions on the factory floor. At the same time, unused data is passed on to the central cloud or data center for further processing.

  1. Supply chains of the future

Another IoT use case is in supply chains, which are increasingly global and complex. Customer requirements evolve rapidly, products have to be procured, shipping and delivery routes have to be coordinated – you get the picture. In response, companies are creating connected enterprise systems and using data modeling as a key part of a broader data management strategy. Low-power IoT devices are also being used to track assets throughout the supply chain, and monitor product quality such as temperature, vibration and container openings. By using IoT-enabled devices and transportation routes, further improvements can be made to route planning by collecting in-transit, supply chain data.

  1. Drones for industrial and search and rescue operations

For cinematographers and photographers, drones have helped record stunning landscapes previously unavailable to visual artists. But, these flying devices aren’t just used for this purpose. Oil rig workers are using drones to complete full rig inspections quicker, without sacrificing worker safety or production downtime. Ecommerce companies are looking into drone delivery of their buyers’ goods to their front doorstep. Even nonprofits are making use of drones to monitor deforestation in environmentally-fragile communities.

Outside of commercial uses, drones are serving the public good in search and rescue missions. These machines are helping search and rescue teams locate victims more quickly, evaluate the status of victims, and map the right path for rescue missions. In dangerous mountain rescues, successful drone operations require high performance and high capacity data storage. Read our latest white paper about how reliable storage makes a difference in life-threatening emergencies.

  1. Smart cities: Energy, transportation, parking and more

One of the most promising IoT use cases is in creating smarter, more efficient cities. Public energy grids can be optimised to balance workloads, predict energy surges, and distribute energy more equitably to customers. The same goes for transportation systems in dense, urban environments. Traffic lights could be synced using IoT to adapt to traffic conditions in real-time. During an emergency, first responders can communicate with traffic lights to synchronise and provide direct access to critical locations. Another possibility is to digitally track parking, so that available spaces are automatically sent as push notifications to drivers looking for a place to park.

  1. Farm to tech to table

Today’s farmers are bringing the power of IoT to streamline their operations. As the use of free-range livestock becomes widely adopted, connected technology can track animals as they graze in open pastures. Smart sensors placed in irrigation systems can reduce water consumption to create just the right moisture level in soil for a given crop. It’s even being used to watch over factors such as humidity and temperature in composting. Additionally, farmers can keep tabs on their equipment, mapping out where each item is, tracking its performance, and carrying out predictive maintenance. Outside of traditional farms, wine producers are using IoT to understand grapevine health and sugar levels in grapes.
