What is the Internet of Things (IoT)?

The Internet of Things (IoT) is a network of physical things or objects, typically embedded with sensors, software, and other technologies to help connect or exchange data from other IoT devices and systems over the Internet. A few examples of these IoT devices are wearable technology, home automation, self-driving cars, smart locks, smart devices, augmented reality, smart thermostats, etc.,

IoT is a multifaceted concept, demanding a deep technical understanding for successful implementation. It has gained significant importance in recent years and is poised to have a profound impact on the future. This life-changing technology can have greater control over their environment by converting physical things into intelligent, interconnected virtual devices.

How Does IoT Work?

IoT is a network of networked devices and sensors that interact and exchange data via the Internet, allowing them to gather, process, and send data without human involvement. IoT devices communicate sensor data by connecting to an IoT gateway, which serves as a central hub for IoT devices to relay data.

The first step is for an IoT device to connect to a local network. The data is subsequently sent to cloud servers through the internet. The cloud servers also provide the information or data generated by the end-user application to the IoT device. This data transmission is a two-way connection that supports the functioning of the IoT system. Here are four key IoT system components that explain how IoT works.

  1. Devices or Sensors: Sensors or devices are the first stage, in this stage as mentioned earlier in the blog, the devices are embedded with sensors that collect real-time information from the physical world. These sensors can locate various parameters including temperature, motion, and humidity.
  2. Connectivity: The second stage of IoT is connectivity. IoT uses different types of communication protocols like Bluetooth, Wi-Fi, cellular networks, and other protocols to transmit data to the cloud or other devices.
  3. Data Processing: The influx of data from sensors and devices would be overwhelming without efficient data processing. This component involves handling, storing, and analyzing the vast amounts of data generated by IoT devices. This data processing can be done in two primary methods one is Cloud-based platforms, where the data is sent to remote servers for processing and storage and the second is Edge computing, in which the data is processed locally on the IoT device or in a nearby gateway.
  4. User Interface: The final component of the IoT jigsaw is the user interface, which connects humans to the IoT ecosystem. Users connect with IoT systems using apps, online interfaces, and even voice commands. These interfaces make it simple to monitor, control, and manage IoT devices and their data.
