What is IOT?
IoT is an acronym of "Internet of Things". Things in this means any physical objects. And hence, essentially IoT means having physical object connect and communicate with each other to achieve certain outcome.
For example, once you reach near to your home, the air condition must start automatically by the time you enter home.
In essence, it means automating entire process of switching on your air conditioner, identifying that you are reaching near and if AC unit allows to control the temperature, then adjusting temperature as per your needs in timely manner.
This means, making AC communicate with you with a device which will confirm that you are near by (GPS, RTLS or your mobile App) and then switching it on and setting it up to desired temperature level.
