Imagine waking up to find the lights automatically on and the room temperature just right for starting the day. It may sound like something out of a science fiction movie, but it's now a reality thanks to the Internet of Things (IoT).

IoT developments not only make everyday life more convenient, but they also play a significant role in streamlining business operations. They increase efficiency, optimise savings, and even facilitate rapid decision-making.

What exactly is IoT technology and how does it work? Learn more about IoT, from its definition, how it works, its benefits, to its applications in various fields in the following article.

What is IoT (Internet of Things)?

The Internet of Things is a technology that allows various devices to connect and "communicate" with each other over the internet. This connectivity allows these devices to provide automatic responses to specific situations/circumstances.

The word "things" in the Internet of Things refers to any device, from smartphones and TVs to washing machines and cars to medical devices. Connecting these devices will undoubtedly simplify various tasks and increase efficiency and convenience.

What are the components of IoT?

The IoT has several key components whose presence is crucial for the IoT system to function. These key components include:

1. Sensors and devices

Sensors and smart devices are key components of IoT systems. This is because sensors are the components that interact directly with the environment to collect various data for processing and triggering automated actions.

IoT sensors are often integrated with smart devices, such as lights equipped with motion sensors. Some commonly used IoT sensors include temperature sensors, pressure sensors, humidity sensors, motion sensors, light detectors, and so on.

2. Connectivity

As the name suggests, IoT systems rely heavily on internet connectivity. For all smart devices to connect and automation to occur, a sufficient internet connection is essential.

However, the internet isn't the only form of connectivity used; it can also be combined with other forms of connectivity. For example, Bluetooth, Z-wave, and Radio-Frequency Identification (RFID) are used.

3. Cloud Storage

With so many sensors, you'll need a lot of storage space. Therefore, IoT typically uses the cloud to store and process data 24/7.

In an IoT system, the cloud is like the brain, not only storing but also continuously processing information. However, for efficiency, it sometimes requires the assistance of edge devices that can process data locally, eliminating the need for forwarding it to the cloud.

4. User Interface

Next, there's the user interface, or UI, which is the part of the system you interact with directly. This UI can take the form of a web-based dashboard, a smartphone app, or a voice interface (e.g., Alexa). Within this user interface, we can do things like:

• View and read device data

• Setting up the device

• Get notifications

• Setting up automation

How Does IoT Work?

Now that we know the components, let's move on to how IoT works. The steps are as follows:

1. Data collected: Sensors and devices collect data on environmental conditions, such as air temperature, GPS position, or movement.

Example: The temperature sensor on the AC detects that the room temperature is 30°C.

2. Data sent via connectivity: Data from sensors is sent to the Cloud via a Wi-Fi network for further processing.

Example: The temperature sensor sends data that the room temperature is 30°C to the Cloud.

3. Data is processed in the Cloud or Edge Device: Simple data is processed directly on the Edge Device. More complex data is sent to the Cloud for further processing.

Example: The system checks the setting that temperature 28°C = AC is on

4. Taking action: The system determines what action to take based on the received data. This action could be, “turn on the AC,” “turn off the engine,” “send a notification,” and so on.

Example: The automatic system turns on the AC.

5. Users get info: You can view data in real-time, make manual settings, and get notifications.

Example: You get a notification that the AC has turned on automatically.

What are the benefits of using IoT?

The use of IoT has various benefits, particularly in simplifying work and increasing convenience. Some of these benefits include:

1. Manage remote devices

IoT allows us to control and operate devices remotely using internet connectivity. Your life would certainly be easier if a robot vacuum cleaned your house while you were away at work.

You also don't need to worry if you leave electronic devices on or forget to turn them off. This is because you have the control to turn them off via your smartphone.

2. Automation and efficiency

Interconnected devices make it easier to set up automation and increase efficiency. Automation also reduces human involvement, saving time and effort on various tasks.

This applies to both increased comfort at home and practicality in business and work. In business, automation also allows you to employ fewer workers, which also contributes to cost savings.

3. Data-based decision making

Sensors and smart devices are key components of IoT systems. With data from various sensors, the system can process situations and respond quickly based on that data.

For example, a factory machine experiences a problem where the temperature rises above normal while it's operating. Using data from sensors, an IoT system can immediately issue a warning or even shut down the machine if it reaches a certain temperature.

4. Increase security

IoT systems are also extremely useful for improving security, whether monitoring homes, offices, or vehicles. In fact, you can monitor all of them simultaneously within the same system.

You can utilise smart cameras, use automatic locks, and even activate notifications for suspicious situations. This way, if a theft or other crime occurs, you can immediately address it.

5. Save energy and costs

Nowadays, we are inseparable from various electronic devices that require electricity. One environmental concern is how to use these devices wisely and support energy conservation.

The good news is, IoT allows you to save energy by automatically limiting consumption. For example, by setting devices to turn on and off automatically according to need.
