IoT Stands for Internet of Things. There has been a huge buzz about IoT recently. IoT has a potential of transforming future.
IoT requires sound knowledge of Embedded Systems and Website Coding Technologies.
IoT is made up of two words primarily, Internet and Things. Things are Electronic Devices and when they are connected to internet to receive and send data a term Internet of Things is used to describe them.
There are 7 Billion Electronic Devices in the world and according to a research this number will be increases to 50 billion by the end of 2020. Most of these devices will be a part of IoT. IPV6 Protocol will be used to provide IP address to these devices.
Explanation: Sensors and other devices are used to detect physical quantities such as:
Data detected from these physical quantities is converted into digital form or machine readable form by integrated circuits.
Digitalized data is supplied to computers by means of communication ports such as USB, Wifi, Bluetooth, Ethernet etc.
Applications or Software are designed to collect and display the data on VDUs.
Data can be transferred to Cloud Hosting Servers. Data on Cloud can be accessed from any other device connected to internet from any location in the world.
Consider an Example to better understand IoT:
You are wearing a smart watch that can detect your health parameters like Blood Pressure, Body Temperature etc. This data is also hosted on cloud and your doctor has the access to your health conditions. He can monitor, warn and consult you in case of problems.
Devices used to collect and convert data into usable formats are as follows:
Internet of Things was first used in 1970 in the Computer Science department at Carnegie Mellon University. Since then IoT is used in following sectors:
IoT has following useful applications:
This is an overview of the topics that are taught in IoT:
