Internet of Things Defined

The Internet of Things refers to the network of physical objects—vehicles, devices, buildings and other items embedded with software, electronics, sensors, and network connectivity—that enables these things to collect and exchange data. The IoT allows things to be controlled or sensed remotely across existing network infrastructure, creating opportunities for direct integration of the physical world into computer-based systems, resulting in improved efficiency, accuracy and economic benefit.

The scope and goals of the IoT are to enable more efficient gathering and sharing of data and improve automation, accuracy, and economic benefit across a wide range of industries. By connecting physical objects to the internet, businesses can gain valuable insights into their operations or customer behaviours to make better decisions. Additionally, governments can use connected devices to optimise services, enhance public safety, and improve environmental sustainability. On the consumer side, connected devices can create a smarter home environment with greater convenience and control.

The characteristics and features of the IoT include multiple network technologies, including Wi-Fi, Bluetooth Low Energy (Bluetooth LE), LPWAN (Low Power Wide Area Network) and 5G/6G. Additionally, the IoT comprises devices with varying levels of intelligence that can collect data from their environment through embedded sensors. This data is then analysed and used to create automated responses or feedback. Finally, the IoT includes applications and services that can be interconnected to provide a seamless experience between multiple devices.

How IoT Works

IoT is a system of interrelated digital machines, computing devices,  objects, animals or people with unique identifiers and an ability to transfer data over a network without human-to-human or human-to-computer interaction. 

IoT connects the physical and digital worlds by enabling devices to communicate with one another. IoT-enabled devices can share data in real-time at any location when connected to a network. It allows for more efficient and effective communication between different system points, often leading to improved outcomes for businesses or consumers. For example, a connected thermostat could send data to the cloud that energy companies can use to manage the heating of large buildings more efficiently. Similarly, a fitness tracker could transmit health data to medical professionals to better monitor and treat patient health. In this way, IoT is changing how we interact with our world and creating a new level of convenience, efficiency, and connectivity. 

With how the Internet of Things works, its process has key components—the sensors, network connectivity, cloud platforms and user interface.

Basic Components of the IoT Ecosystem

The IoT ecosystem comprises four basic components: sensors, network connectivity, cloud platforms and user interface. Knowing how they work, you will better understand the Internet of Things.

1. Sensors — Data Collection

Sensors are the first step in any IoT system. They collect data from their environment, converting physical qualities into digital signals that other network components can use. For example, a temperature sensor might detect changes in the air and send a signal to other devices when it falls below a certain threshold. This data can then perform tasks such as adjusting the temperature in a room or sending an alert when something needs attention.

2. Network Connectivity — Data Sharing

Network connectivity is essential for the IoT ecosystem to work. It allows devices within the system to communicate and share data. Network protocols like Wi-Fi, Bluetooth, and Zigbee are common in IoT systems. For example, a sensor might detect a temperature change and then use Wi-Fi to send this information over the network to a cloud platform for further processing.

3. Cloud Platforms — Data Processing 

Cloud platforms store and process data collected by sensors. These platforms analyse the data and make decisions based on the results. For example, a cloud platform could use machine learning algorithms to detect patterns in sensor data and then take appropriate action.

4. User Interface — Transmits Data

The user interface is the final component of an IoT system. It allows users to interact with the data collected by sensors and make decisions based on the information they receive. It could include something as simple as a mobile application that allows you to adjust the temperature in your home or a more complex dashboard that shows detailed analytics about how your devices are performing.

IoT applications are also another way to understand how IoT works.
