What is IoT?

IoT, or the Internet of Things, is a broad term for the billions of physical items—like appliances and industrial equipment—that are connected to the internet. These items gather and share data with other devices and systems online. 

Although the concept of IoT has been around since the 90s, it’s only recently become more feasible thanks to several technological advancements, including:

• Cheaper and more reliable sensors
• More available cloud computing services
• Progress in AI and machine learning

An IoT device varies widely, from simple household gadgets to complex machinery in factories. Each device has its own unique identifier (UID) and can send data independently, without human help.

Different Types of IoT

The ways that networks, communication, and connectivity protocols work largely depend on the type of IoT application being used. Since there are numerous IoT devices, there are also various types of IoT applications, each tailored for different uses. Here are some of the most common types:

• Consumer IoT: Used daily by consumers, such as in home appliances, voice assistants, and lighting systems.
• Commercial IoT: Often used in the healthcare and transportation sectors, for example, smart pacemakers and monitoring systems.
• Military Things (IoMT): Employed in military contexts, like surveillance robots and biometric wearables for soldiers.
• Industrial Internet of Things (IIoT): Used in industrial settings, like manufacturing and energy, involving things like digital control systems, smart farming, and industrial data analysis.
• Infrastructure IoT: Important for smart city connectivity, including sensors and management systems for urban infrastructure.

What are IoT Devices?

IoT devices are physical items like sensors, gadgets, appliances, and various machines that gather and share data via the Internet. They are designed for specific tasks and can be integrated into other IoT devices. For instance, an IoT device in your car can detect traffic ahead and automatically notify the person you’re meeting if you’re going to be late.

How An IoT Device Works

The IoT device, despite its varied applications, generally follows a consistent operating model that hinges on the interaction between hardware, network connectivity, and software control mechanisms. Here’s a detailed look at how these devices typically function:

#1 Sensing

At the core of an IoT device is its ability to detect and measure changes in the environment. This is achieved through sensors that can monitor a wide range of physical conditions like temperature, motion, light, etc. These sensors gather data from their surroundings, which is the first step in an IoT device’s workflow.

#2 Processing and Control

The data collected by sensors is processed by an integrated CPU (Central Processing Unit). This microprocessor interprets the sensor data based on programmed instructions. Depending on the complexity of the IoT device, this processing might be simple or involve more sophisticated data analysis and decision-making processes.

#3 Network Connectivity

For an IoT device to send and receive data, it needs to be connected to a network. This is typically facilitated by a network adapter within the device. The connectivity could be via Wi-Fi, Bluetooth, Ethernet, or other communication technologies. To effectively communicate across a network, the device often obtains an IP address from a Dynamic Host Configuration Protocol (DHCP) server, which assigns network addresses to devices on a network.

#4 Software Interface and Configuration

An IoT device usually requires a software interface for user interaction and configuration. This might be an app on a smartphone or tablet that lets users manage the device’s functions. This software enables users to set preferences, control device operations, and view data collected by the device.

#5 Web Servers and Autonomous Control

Some IoT devices come with integrated web servers. This setup can streamline operations by eliminating the need for external applications. For example, a smart light system with an integrated server might automatically turn lights on or off when it detects a person entering or leaving a room, based on motion sensors.

5 IoT Devices Examples You Should Know

#1 Home Security Systems

The IoT device plays a crucial role in enhancing home security. Examples include a range of IoT-connected sensors, lighting systems, alarms, and cameras, all manageable from a smartphone. These devices work collectively to offer continuous surveillance and security.

#2 Health and Activity Monitoring

In the realm of personal health, IoT technology includes smart security cameras that send real-time alerts, contributing to homeowner peace of mind. Additionally, activity trackers are pivotal IoT devices that monitor vital health metrics such as blood pressure, physical activity, appetite, and oxygen levels, allowing users to keep a close eye on their health status.

#3 Industrial Security and Safety Solutions

IoT technology is instrumental in industrial safety, employing IoT-enabled detection systems, sensors, and cameras specifically in restricted areas to prevent unauthorized access and monitor safety conditions. These devices are adept at detecting pressure anomalies and small chemical leaks, addressing them proactively to avert larger-scale incidents.

#4 Augmented Reality Wearables

Augmented Reality (AR) glasses exemplify advanced IoT wearables. These glasses overlay digital information like 3D animations and videos onto real-world views, integrated directly into the lenses. This technology not only enhances user interaction with their environment but also facilitates seamless access to Internet applications.

#5 Structural Monitoring

Motion sensors represent another critical application of IoT devices, capable of detecting structural vibrations in buildings, bridges, and dams. These sensors are essential for identifying potential failures and disturbances early. They are also used in monitoring geologically unstable areas prone to natural disasters such as floods, landslides, and earthquakes.
