The Internet of Things is rising as the third wave in the advancement of the internet. Internet of things (IoT) is relied upon to massively affect consumer items, business and more extensive culture, however these are still early days. Given its potential for wide applications to practically all verticals and parts of business, enterprises, fabricating, consumer products, supply chains, and so forth. IOT in general is exceptionally wide region. We see the IoT as billions of smart, associated "things" (a kind of "all-inclusive worldwide neural system" in the cloud) that will incorporate each part of our lives, and its establishment is the insight that installed handling gives. The IoT is contained brilliant machines cooperating and communicating with other machines, objects, environments and infrastructures. Accordingly, immense volumes of information are being produced, and that information is being handled into helpful activities that can "order and control" things to make our lives a lot simpler and more secure—and to diminish our effect on the earth. The inventiveness of this new time is limitless, with astounding potential to improve our lives. This paper centers around the utilization of IOT devices in different platforms and the parameters that should be considered to assemble the IOT devices. Additionally, I have talked about the different security challenges and have made sense of the best answers for them.
