In simple words IoT is the interconnection of different type of devices (Any device) with humans and with each other, for examples your watch may alert your health care provider when your sugar level is rising beyond some specific value consequently your vital signs are sent to your family doctor and based on his response insulin is injected to your body to lower the sugar level, this all process may occur without any human intervention as your family doctor may be an AI (Artificial Intelligence) and not a human doctor.
