Got a smartphone? How about an Apple Watch? Maybe even a Nest thermostat at home? If you have any one of these devices, it puts you into the connected category of owning an Internet of Things (IoT) device.

To keep it simple, an IoT device transmits data. It’s transformative for consumers but also used in transportation, logistics, energy, retail, waste and water management, IT infrastructure, and autonomous vehicles, according to a report by

It’s a fast-growing, global industry — there were 11.3 billion IoT devcies last year and in 2030 experts project that number to increase three-fold to 29.4 billion, the report said. One of the most common IoT devices, smartphones, will account for 17 billion of those devices in 2030.

What Are IoT Devices? 

IoT devices are nonstandard computing devices that connect wirelessly to the Internet or a local network hub, TechTarget reports. These remotely controlled devices have the ability to transmit and recieve data from other devices. Some everyday examples might be a car, doorbell or a even a refrigerator.

These IoT devices can be hardware, sensors, gadgets, machines, or appliances that communicate over networks or the Internet through applications and their programming, according to a glossary by processor design company Arm. These smart devices turn ordinary objects into tools that can provide information, states a Cert NZ report.

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, according to Cert NZ. 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, Cert NZ said in its report. 

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 too if they are hacked or compromised. 

Here are 20 examples of IoT devices.


20 Top IoT Device Examples
