• Cloud Computing Platforms: They store data collected through IoT devices for processing or identifying errors within
the system.
• Control Unit: It analyses and processes data from the sensors and carries out necessary operations.
• Low cost and low power consuming electronic system.
Applications of IoT
IoT technology finds its application in a wide range of fields which are listed as follows:
• Smart cities: IoT applications are implemented in smart cities for intelligent traffic management, improved health
diagnosis and services, smart water supply, scheduling waste collection depending on the fill level of the bins,
automated meter reading of water, electricity and gas of the consumers, smart parking facility, automated smart
lighting controls and many more such applications.
• Healthcare: Physical fitness devices and activity trackers like smartwatches and monitors easily provide their users
with data pertaining to their blood pressure, heart rate, and activity of users and also update them on a daily basis.
They can even send messages to family members or even contact appointed doctors in case of emergencies.
• Transportation: Driverless cars (autonomous or self-driving cars) use IoT during navigation.
• Daily activities: Household appliances like smart refrigerators, smart TV, smart dishwasher, smart microwave, etc.
can easily connect to the internet through wi-fi and interact with the owner through smartphone or tablet. They
can customize the temperature of the compartments, alert you when your stock is low, automatically turn off when
a task is complete and do many other activities which make our lives a lot easier.

14.1.3 Virtual Reality
Have you ever come across 7D cinema? If not, then it’s time to be aware of this new term, which is an upgraded version
of the 3D, 4D, 5D and 6D cinemas. It is a combination of 3D images and effects produced by special equipment which
affects our sense organs. Other than the 3D images, we can sense wind blowing, rain falling, snow or bubble flying and
the motion of the dynamic seats; all appear to be happening in front of us which takes us to a fantasy world. We can
even smell or taste a virtual object. We, thus, experience a real-world-like affect though the environment is virtual.
Definition
The Merriam-Webster dictionary defines virtual reality as “an artificial environment which is experienced through
sensory stimuli (as sights and sounds) provided by a computer and in which one’s actions partially determine what
happens in the environment.”
Virtual reality (VR) seeks to create a realistic 3D environment using interactive hardware and software, that human
organs sense as real and even interact with it in realistic ways.
