Internet of Things

Definition

Ashton initially defined it as:“today’s computers and the Internet are almost entirely dependent on the human to provide information”. There are about 50 petabytes (a petabyte equals to 1024 terabytes) of data on the Internet and most of them are obtained and established by people initially by way of typing, recording, photographing or bar code scanning, etc. A node in the largest number and of the highest importance has been ignored in traditional Internet blueprint, which is the people.

Problem

The problem is that people’s time, energy and accuracy is all limited and they are not suitable for intercepting information from the real world. This is a big problem. We are living in a material world where we cannot take the virtual information as food to eat or as firewood to burn. The ideas and information are very important, but the material world is more fundamental. Today’s information technology depends on the information produced by human so much that our computers know more about ideas than materials. If the computer can obtain all kinds of information available in the material world without our help, then, we would be able to track and measure the materials to reduce waste, loss and consumption. We would know when the articles need to be replaced, repaired or recalled and whether they are new or overdue.

Potential to change the world

IoT has the potential to change the world, just like the Internet, and is even more far-reaching. This technology-combined method can also be combined with the traditional market to change the traditional market into a big step towards the technology through the combination of Arduino, IoT and other technologies.
