What Is IoT And How It Works?

The Internet of Things (IoT) refers to millions and billions of devices connected to the internet around the world for sharing data. Due to cheap computer chips and the availability of the internet everywhere, it makes it possible to turn everything from a needle to a big city into an IoT.

When an object is connected to the internet, it can either send or receive information or works in both ways. This ability makes them smart, and that is why IoT matters. IoT provides people and businesses a better control and insight over objects as well as the environment.

With the arrival of IoT, the world around us will be smarter and responsive than before, merging the physical and digital universe. There are four main components in an IoT system. These include devices/sensors, connectivity, stream processing, and user interface.

  • First, a device or sensor will collect data from the environment like any temperature sensor or GPS.
  • In the second step, the sensors will send data to the cloud. Sensors and clouds will be connected through Bluetooth, Wi-Fi, satellite, cellular, Ethernet, or LPWAN (low-power wide-area-networks).
  • The connectivity selection depends on range, bandwidth, and power consumption requirements. When a cloud receives data, it will process it. For instance, the temperature sensor will check whether the reading is in an acceptable range or complex.
  • The end-user gets that information via email, text, or any other alert. For example, when the temperature in cold storage cross maximum range, the alarm will buzz to notify the user. The user will be able to check the system proactively on an interface.

These are basic elements of IoT. Depending upon the application, the user can adjust the system remotely via a phone app, or they automatically adjust through the predefined rules.

History of IoT

In 1832, the concept of connected devices emerged with the invention of the first electromagnetic telegraph. The two machines could communicate directly with the help of the telegraph by transferring electrical signals.

However, it actually begins with the arrival of the internet, an essential component of IoT. In the 1980s, the Coca-Cola vending machine was the first connected device at Carnegie Melon University. It was operated by the local programmers.

Micro-switches were integrated into the vending machine and used the internet to check if the cooling device is keeping the drinks cold as well as the availability of the Coke cans. After this invention, the studies on the development of internet-connected machines fostered rapidly.

For the very first time, John Romkey, in 1990, connected to the internet with TCP/IP protocol. After a year, the University of Cambridge researchers brought forward the idea of a coffee monitor web camera. It was aimed to monitor the amount of coffee in the coffee pot of local computer lab.

Who Invented The Term IoT?

In 1999, Kevin Ashton, a visionary technologist, coined it as ‘the internet of things.’ He was giving a presentation to Procter and Gamble, where he defined IoT as a technology for connecting devices using RFID tags for their supply chain management.

The term ‘internet of things’ widespread use at the beginning of the 21st century by media like Forbes, The Guardian, and Boston Globe. The interest in IoT increased steadily, and in 2008, the first international conference on IoT held in Switzerland.

During this period, an internet-connected LG Electronics refrigerator in 2000 and a robot named Nabaztag in 2005 who was able to share the latest news were notable developments.

In 2011, the Gartner hype Cycle supported the IoT boom for emerging technologies. IoT central, a network layer protocol IPv6 was launched in the same year. Since then, Global tech tycoons like Google, Apple, Cisco, and Samsung are putting their efforts on the production of IoT devices and sensors.

All this is enough to tell how important IoT is for developers.

IoT Use Cases: What Are The Advantages Of IoT?

Now, smart sensors are integrated into billions of devices across the globe and generate massive data. It covers almost all areas, including military, smart building, retail, manufacturing, agriculture, energy, healthcare, logistics, smart vehicles, and transportation.

Here are some major use cases of the internet of things.

Connected Autonomous Vehicles: In the future, vehicles will have level 5 autonomy means fully autonomous without any human intervention. Cars will even communicate with each other, road infrastructure, and perhaps with a pedestrian by using V2X (vehicle-to-everything) technology.

Today, car manufacturers are working on self-driving technology levels 2, 3, and 4. Radar cameras, LIDAR, and other onboard sensors will collect information about traffic conditions, road conditions, and will inform inappropriate driving conditions.

Smart Security for Homes and Businesses: The smart security systems can collect, store, and perform analysis on video streams. With high-resolution 4K video cameras and machine learning, the system will carry out motion detection and pattern recognition.

Smart Wearables: The wearable market is flourishing with the influx of personal devices such as fitness trackers and smartwatches. Consumers want a seamless connection between their smartwatches and smartphones to monitor, manage, and secure data.

This especially includes health data. A recent report predicts that by the year 2022, the wearable industry will sell 233 million units annually.

Connecting Homes to IoT: With smart speakers, anyone can command household electronics to do a variety of functions. For example, to instruct dimming the room lights, setting thermostat temperature, etc.

Future Supply Chains: IoT supply chain use case is increasingly complex and global. Low-power IoT sensors can track assets and monitor the quality of the product, such as temperature, expiry, vibrations, etc. throughout the supply chain.

Smart Cities: Creating smarter and more efficient cities is another most promising IoT application. It includes optimization of energy grids, transportation, and parking systems.

So these incredible applications of IoT are enough to picture the world of tomorrow, making IoT for developers inevitable.
