Internet of Things (IoT) Technologies

by Muhammad Yousuf Ali

Internet is considered one the of important and essential information and communication medium for the transmission of the information. There are different gadgets use for the internet. An Internet of Thing (IoT) is all about internet devices and digital devices who support internet services or involve in internet services. This article discuss about the internet of things.

  1. What is Internet of Things (IoT)?

The Internet of things (IoT) describes physical objects (or groups of such objects) with sensors, processing ability, software and other technologies that connect and exchange data with other devices and systems over the Internet or other communications networks. (Gillis, Alexander, 2021).

An IoT ecosystem comprises web-enabled smart devices that use embedded systems, like processors, sensors, and communication hardware, to collect, send, and act on the data that they acquire from their environments. These devices share the sensor data they collect by connecting to an IoT gateway or other edge device. The data is further transferred to the cloud to be analyzed or analyzed locally. Often, these devices communicate inter link with other devices and act on the information they get from one another. 

What are the technologies enabling the internet of things (IoT)?

  1. Sensors and actuators
  2. Connectivity technologies
  3. Cloud computing
  4. Big data analytics
  5. Security and privacy technologies

Internet of Things applications apply through different technologies.

  • Sensors and actuators: Sensors are devices that can detect changes in the environment, such as temperature, humidity, light, motion, or pressure. Actuators are devices that can cause physical changes in the environment, such as opening or closing a valve or turning on a motor. These devices are at the heart of IoT, as they allow machines and devices to interact with the physical world. Automation is possible when sensors and actuators work to resolve issues without human intervention.
  • Connectivity technologies: To transmit IoT data from sensors and actuators to the cloud, IoT devices need to be connected to the internet. There are several connectivity technologies used in IoT, including Wi-Fi, Bluetooth, cellular, Zigbee and LoRaWAN.
  • Cloud computing: The cloud is where the vast amounts of data generated by IoT devices are stored, processed and analyzed. Cloud computing platforms provide the infrastructure and tools needed to store and analyze this data, as well as to build and deploy IoT applications.
  • Big data analytics: To make sense of the vast amounts of data generated by IoT devices, businesses need to use advanced analytics tools to extract insights and identify patterns. These tools can include machine learning algorithms, data visualization tools and predictive analytics models.
  • Security and privacy technologies: As IoT deployments become more widespread, IoT security and privacy become increasingly important. Technologies such as encryption, access controls and intrusion detection systems are used to protect IoT devices and the data they generate from cyber threats.
