Got a smartphone? How about a TV that connects to the internet? Maybe even a thermostat you can control from an app? If you have any one of these items, it puts you into the category of owning an Internet of Things (IoT) device.

What Are IoT Devices?

IoT devices are hardware that have a wireless network connection and are integrated into equipment or other devices, so they can receive and share data. Examples of IoT devices include sensors, actuators, appliances and gadgets.

IoT devices aren’t just used by consumers. They’re also transforming industries like logistics, retail, energy, IT infrastructure and autonomous vehicles. As a result, the number of IoT devices is expected to surpass 29.4 billion by 2030. 

 

What Are IoT Devices? 

IoT devices are hardware that connect wirelessly to the internet or a local network hub. These remotely controlled devices have the ability to transmit and receive data from other devices. Some everyday examples include a smart car, smart doorbell or even a smart refrigerator. Through IoT devices, ordinary objects become tools that provide information.

How Do IoT Devices Work? 

Many IoT devices gather information via their sensors and then use software to analyze it and determine what decisions to make based on the data.

These devices usually connect to a central server to get more information. They also compare and transmit data to public websites and services to collect data, as well as connect to a messaging server that can email, text or call. IoT devices can also connect to other IoT devices via the same wireless network to instruct them on what to do. 

Although IoT devices can make tasks easier, more convenient or expand the capabilities of the task, these devices can also pose a security and safety threat if they are hacked or compromised.

With AI features, users can preview and edit photos, summarize stories in a few short bullet points, reply quickly with chat recommendations and translate text messages into another language in real time with Live Translate. Users can also circle objects in videos with the built-in S Pen or their finger to activate an immediate Google search.

Smart Alarm

Google’s Nest Protect is a smart smoke and CO2 detector that provides audible warnings and explains where in the house smoke or CO2 is located. Once they’ve linked Nest Protect to a smartphone, users can receive mobile alerts when they’re on the go and silence their smart smoke alarm with a tap. Nest Protect also communicates air status with green, yellow and red colors for easy monitoring. 

Smart Refrigerator

Samsung has also upgraded its smart fridges, supplementing IoT technology with AI features. The company’s Bespoke refrigerators can connect to a smartphone app, so users can view the inside of their fridge and preheat the oven with a few taps. With the addition of AI, these fridges can now identify individual food items, alert users when foods are about to expire and even recommend recipes upon accessing a user’s Samsung Health profile.

Autonomous Vehicle

Waymo’s autonomous ride-hailing fleet prioritizes safety during navigation with the help of lidar sensors attached to each vehicle. These sensors provide a 360-degree view of a vehicle’s surroundings, allowing the company’s self-driving cars to remain aware of what’s around them. Combining sensor data with machine learning, Waymo’s vehicles can quickly detect objects and pedestrians and take appropriate action. 

Fitness Mirror

FORME offers two smart mirror options for home workouts in the FORME Studio and the FORM Lift, which comes with its own strength training arms. Both smart mirrors are equipped with a high-definition touchscreen and enhanced audio. Once connected to the FORME app, these smart mirrors can provide personal coaching, track progress, display on-demand workouts and play songs from popular music apps. 

Smart Lamp

The Philips Hue Bridge and a Bluetooth-controlled system allow you to unlock all the features in the Philips Hue IoT system, such as controlling your smart lights and syncing your lights the games, music or movies. Paired with Philips Hue’s portable smart lamp, this system enables users to set the mood with different lighting and light effects. 

Smart Lock

BenjiLock has designed two smart locks — one is tailored to TSA requirements and stores up to five fingerprints while the other caters to daily usage and stores up to 10 fingerprints. All it takes is a simple tap and each device unlocks upon recognizing a user’s fingerprint. Both locks come with rechargeable lithium-ion batteries, and the daily-use smart lock can last up to one year on a single charge. 

Smart Toy

Sphero’s Sphero Mini is a compact sphere intended to make STEM education and coding more enjoyable for kids through hands-on learning. The toy works in tandem with the Sphero Edu and Sphero Play apps, which users can access on common mobile and laptop devices. Users can then play games to learn core subjects and computer science concepts to build well-rounded skill sets.
