Internet of things

The internet of things (IoT) is reshaping how the world connects and communicates through data. Far more than a collection of smart gadgets, IoT is an intelligent network of devices and sensors integrated into systems that spans homes, industries and entire cities. This convergence of the physical and digital enables real-time insights and automation — driving innovation in everything from industrial automation to smart urban infrastructure.

What is the internet of things?

Internet of things definition: The internet of things is an interconnected network of physical devices — ranging from industrial machinery and infrastructure to vehicles and household appliances — that communicate and share data over the internet.

The foundational technologies underpinning internet of things (IoT) have transformed how the world collects and uses data, enabling new levels of automation, and operational insight across industries and daily life.

In practice, internet of things systems operate across a wide range of environments — from constrained, power‑efficient devices in urban areas to highly resilient platforms deployed in extreme and remote conditions. This includes everything from sensors embedded in consumer devices and industrial equipment to connected systems operating in mobile and airborne applications, and even in orbital environments.

This edge‑to‑orbit scope reflects the breadth of IoT deployments, from network‑edge devices that generate and process data locally to aerospace and space‑based platforms operating under extreme conditions. Together, these systems span the full continuum of data generation and processing, requiring technologies that can operate reliably across different performance, endurance, and environmental requirements

Traditional products, such as watches, have evolved into smartwatches and household devices like vacuum cleaners have evolved into robotic devices. Consumer and business systems augment our lifestyles as assistants, productivity accelerators and automation agents, while industrial systems now rely on IoT for predictive maintenance and operational efficiency. As billions of devices come online, IoT is accelerating the development of smart cities and intelligent infrastructure, deepening our society's interconnectedness and shaping the future of how we live and work.

How does internet of things work?

IoT devices function within a coordinated ecosystem. Sensors and embedded software collect data, connectivity enables transmission, gateways manage data flow, and applications analyze information to trigger action

Each part of this ecosystem must function seamlessly to deliver the benefits of IoT.

• Sensors: The "sense organs" of IoT devices, gathering data from their environment — like temperature, motion or heart rate.
• Connectivity: Devices use internet connections (Wi-Fi, cellular, etc.) to send data to other devices or cloud applications.
• IoT gateway: Organizes and directs the flow of information between devices and applications, ensuring data reaches the right place for analysis.
• Data analysis: Applications process and analyze the collected data, turning raw information into actionable insights — such as alerting you to a change in your home's temperature or tracking your sleep patterns.

What is the history of the internet of things?

• 1990s, The coining of internet of things: The late 1990s was the first instance of internet of things being titled, following the increase of the use of the internet as a whole. The definition of the internet of things has changed and evolved over the years.
• 2000s, 'tagging of things': Tagging of things gained traction, with technologies like RFID enabling businesses (e.g., Walmart) to track inventory efficiently. This era saw the rise of machine-to-machine (M2M) communication and the first industry consortia working toward IoT standards.
• 2010s, IoT products: During the 2010's, the internet of things expanded into consumer and industrial products, making connected devices a part of everyday life and enterprise operations. Focus shifted to seamless integration and improved user experiences. This period also marked the emergence of cloud computing and analytics to extract value from IoT data.

What are the key types of internet of things?

With the proliferation of smart devices, there are various types of internet of things devices available, supporting a variety of industries.

• Consumer IoT: Devices for personal and home use, including smartwatches, fitness trackers, smart speakers and connected appliances. A common example is a smart thermostat that learns household routines and adjusts temperature automatically.
• Commercial IoT: Solutions for business environments such as inventory tracking, smart lighting and connected point-of-sale systems. In retail operations, IoT sensors are often used to monitor stock levels and automate reordering
• Industrial IoT (IIoT): Enhances manufacturing, healthcare and agriculture by connecting machinery, sensors, and analytics platforms to monitor equipment health, reduce downtime, and optimize maintenance.
• Internet of military things (IoMT): Connects military devices and systems to improve situational awareness, system coordination, and mission responsiveness in dynamic environments.

How is the internet of things used?

IoT's impact is visible across a wide range of domains, driving innovation and efficiency in both everyday life and enterprise environments:

• Smart homes: Devices like smart security cameras, doorbells, thermostats and lighting systems create safer, more convenient living environments by automating tasks and enabling remote monitoring.
• Commercial spaces: IoT automates routine tasks, improves logistics and enhances customer experiences in offices, warehouses and retail stores. Connected sensors streamline inventory management and drive sustainability by reducing waste.
• Industrial applications: The industrial internet of things (IIoT) powers predictive maintenance, energy efficiency and process automation in manufacturing, agriculture and utilities. Drones equipped with IIoT sensors are revolutionizing crop monitoring, infrastructure inspection and delivery logistics.
• Healthcare: Wearables and remote monitoring devices help track patient health, deliver personalized care and enable real-time alerts for medical professionals.
• Aerospace and defense: Internet of things technologies play a critical role across aerospace and defense environments, where connected systems must operate reliably under extreme conditions. IoT enables real‑time situational awareness, system health monitoring and coordinated operations across vehicles, platforms and infrastructure. Connected sensors, autonomous systems and secure communications support mission planning, logistics, surveillance and decision‑making in defense applications, while also enabling aerospace use cases such as aircraft monitoring, satellite systems and space‑adjacent platforms.
• Exploration and remote operations: IoT technologies enable autonomous vehicles, drones and sensor networks to explore remote or hazardous environments — from deep-sea research to planetary exploration. These systems collect and transmit data in real time, supporting scientific discovery and safe operations in challenging conditions.
• Search and rescue & disaster response: Embedded IoT sensors and communication devices are critical in survival and emergency scenarios. Environmental sensors, edge devices and smart equipment management platforms enable rapid detection of hazards, real-time location tracking and efficient coordination of rescue teams.

IoT-powered systems can monitor conditions, automate alerts and optimize resource deployment, improving response times and outcomes in disaster situations. For example, smart emergency equipment management platforms and sensor networks can provide rapid retrieval of critical data, guide evacuation and ensure equipment integrity across large facilities. Acoustic sensors and IoT platforms can detect early equipment failure, stream real-time data and support decision-making during emergencies.

• Emerging technologies: IoT is foundational to the rise of autonomous vehicles, smart grids and environmental monitoring systems, connecting billions of devices and shaping the future of how we live, work and interact with technology.
