What Is The Internet of Things?

Imagine when your pillow can elevate the snore or even checking your health. Imagine when all of your appliances connected and you can check, monitor even control it via smartphone. Imagine if you can control your own house and everything within it. The examples I give to you just one of the implementation of Internet of Things.

Yup, Internet of Things become interesting topic this year. We are not just talking about human interaction with computer or human with appliances, but we are talking about computer no… but machines communicate with other machines. Before talking further, we need to know where and when the of terms of Internet of Things started.

The terms of the Internet of things come from Kevin Ashton when he made a presentation at P&G in 1999. Ashton said in RFID Journal, today computers -and therefore the Internet- are wholly almost dependent to human beings for information. Nearly all of the roughly 50 petabytes (a petabyte is 1,204 terabytes) of data available on the Internet were first captured and created by human beings- by typing, pressing a record button, taking digital pictures or scanning a bar code. Conventional diagrams of the Internet include servers and routers and so on, but they leave out of the most numerous and important routers of all: people. The problem is, people have limited time, attention and accuracy– all of which means they are not very good at capturing data about things in the real world.

When we talk about accuracy, computers are better than people. People are physically limited in attention and time. Different than people, computer can survive in extreme condition without food and water.

Many researchers and practitioners studying this technology and trying to create and connecting all devices. Communication is important thing like people talk each other. If you want people to know what your talking about you need to communicate with them using the same language. This also applies to IoT. To work and communicate with other devices, IoT using a protocol. One of them is MQTT.

Refer to mqtt.org, MQTT stands for MQ Telemetry Transport. It’s a extremely simple and lightweight messaging protocol created by Dr Andy Stanford-Clark of IBM and Arlen Nipper of Arcom (now Eurotech) in 1999. Here is an example of the Internet of Things implementation.
