What is Internet of Things

Today we can't live without the Internet. The  most advanced development of internet technology is the Internet of Things. Various objects, devices, and sensors are become available to be accessed via internet. Cisco has predicted that there will be around 50 billion devices will be connected to internet in 2020.

Casagras project define IoT as a global network infrastructure, linking physical and virtual objects through the exploitation of data capture and communication capabilities. The infrastructure includes existing internet and its network development.  It will offer specific object identification, sensor and connection capability as the basis for the development of independent cooperative services and applications. 

Examples of IoT devices : smartglass, smartwatch, RFID, smarthome, household, smart-TV, modern car, weather station, and medical instrument.

I will give a few examples what are very real examples of what the Internet of Things is already doing: Wearable devices such as smartwatch and  fitness trackers collect data on how many steps you take, how well you sleep, how many calories you consume and much more. The next  progress
in wearable technology  such as smart watches – Apple’s version was launched in 2015. These watches collect data on almost anything – your geographical location, your speed or your body functions – and this data can be synced to phones or tablets and analyzed in apps.

Sensors are everywhere. The oceans are full of sensors that track sea temperature and currents. A number of companies put sensors into farmland to track soil health and predict the right level of fertilizers required to obtain an optimal crop. Your toothbrush can even sense how well you’re brushing and send the analysis to your smartphone so you can improve your brushing technique.
