                               Age of Internet of Things(IoT)









               Today is Monday. The traffi c is backed up, so you have to get up approximately 20 minutes earlier,
            or you’ll be late to school. Receiving the information, your smartphone rings the alarm 20 minutes
            prior to the originally set time, and the lights turn on to wake you. Thank the phone and lights; you get

            to school at the right time.
               You might wonder what this scene is all about. This is not a part of a science fi ction fi lm. Soon, most
            objects around you will be able to share information, connected by the Internet, and you’ll live a whole
            new life. The era of Internet of Things has begun.


               What is the Internet of Things?


                                                                 The Internet of Things is basically the concept
                                                               of connecting any device to the Internet. It is

                                                               considered as a new way of communication

            these technologies, objects can exchange their physical sensing information such as their temperature,
            humidity, location or heat.
