What is IoT?
Internet of Things (IoT) is the network of physical objects or things that are connected to the internet. The objects can be anything such as mobile phones, washing machines, car, headphones, lamps, wearable devices, house-holding items (Home automation devices), and even human, etc.
The main objective of IoT is to enable the objects communicate, sense or exchange data with each other. The interaction can be happened between human-human, human-things (objects), and things-things. Here, the devices connect to the internet through a technological communication mode such as Wi-Fi, Bluetooth, Bluetooth Smart, iBeacon, NFC, and Zigbee Wireless, etc.
Generally the mobile phone is used as a bridge between the devices, through which the devices communicate to the internet and communicate with each other. The administrator of these devices can access the data collected by these devices or manage the devices from anywhere using mobile app or mobile browser.
Example for IoT: Let’s say you are on your way to a meeting by car, you get stuck in the traffic. If your car has access to your schedule or mobile calendar, it can notify the concerned person that you will be late (If your car is embedded with a location tracking sensor, and programmed with the actual time taken to reach the office). Here, the actions can be automatic or manual between the things-things and human-things.
