The Internet of Things (IoT) is the network of physical objects (or things) equipped with sensors, software, etc., to connect and exchange data with other devices and systems over a wireless network without human intervention. These physical objects or devices range from ordinary household objects to sophisticated industrial tools. When something is connected to the Internet, that means that it can send information or receive information, or both. This ability to send and receive information makes things smart. With more than 10 billion connected IoT devices today, experts expect this number to grow to 22 billion by 2025.
Having a quick look at history reveals, this technology was firstly used in the early ’90s by Coca-Cola. A modified vending machine at Carnegie Mellon University connected to ARPANET (the old version of the Internet) was the first to use this technology; its purpose was to report its inventory and whether newly loaded drinks were cold or not. Later the modifications were introduced in both the Internet and this technology, so IoT technology started to groom in coming decades.
To get your journey started with IoT, you need two important things 1) An electricity supply 2) Connectivity, i.e., the Internet. Electricity is becoming an inseparable part of human life, and it seems there is no alternative. The connectivity of these devices can be chosen depending on our purpose. The main factors influencing are distance and speed/ power. Depending on that, we can select the option of WiFi, Bluetooth, Cellular connection or satellite connection, etc. There also exist multiple subcategories to these options.
In today’s world, the personal or business possibilities are endless. A ‘thing’ can refer to a connected medical device, a biochip transponder, a solar panel, different sensors, or any object to gather and transfer data over a network. So, IoT is being used in many sectors due to its wide applications. The extensive set of applications for IoT devices is often divided into consumer, commercial, industrial, and infrastructure spaces.
