2. Internet of Things
• Internet of Things, which is usually abbreviated as IoT,
can be described as internet for everything.
• Everything here literally means everything, so that to
put it simple, IoT is an internet technology that is used
for every aspect in this life, especially works that are
usually done manually with human labors.
• It can also be considered as automation of many
works, from insignificant ones, such as turning lights on
and off, to significant ones, such as irrigating some
areas. So, with IoT, our life will be much simpler and
easier.
4. Security in IoT
• Although the results of the utilization of IoT seem to be
a bit too good to be true, there must be a drawback
from such technology, just like every technology that
has been invented before has. In the case of IoT, the
most visible drawback in this technology is its security.
• It has become known by everyone that internet
technology is vulnerable to irresponsible people,
especially hackers who hack into a system through the
internet to get their personal gains or those who are
ordered to do so by the ones who want to break the
system.
5. Contd..
• There are two main aspects that are vulnerable in IoT: communication and
data storage. It cannot be denied that most of communications that we do
nowadays use internet technology.
• They are of course far cheaper than using other forms of communication
at the cost of having vulnerable security.
• Not only that, people nowadays rely so much on the internet to store their
data (which is usually called cloud storage) due to the huge demands of
data storage that increase day by day.
• Of course, they know the risk of having a security breach that can cause
their communications to be bugged or their stored data to be stolen but it
does not stop them from using the internet to save them from many other
visible troubles.
• Until now, the security in IoT remains an issue, although there have been
many IT experts who work relentlessly our there to maintain the security
in IoT.
6. Cloud based smart parking system
based on IoT
• Another example of the application of IoT is a
cloud based smart parking system based on IoT.
• This idea of a smart parking system appears due
to the difficulty that many people face when they
try to find a parking space, especially in rush
hours in big cities.
• Many people, especially VIP ones, waste their
time looking for parking spaces every day and
that can really affect many aspects in their life.
7. Contd..
• With a cloud based smart parking system, we can
get the information we need regarding a parking
space, such as the availability of a parking space
in a parking lot as well as the ability to book the
empty parking space beforehand.
• So, with this system, we will rarely see people
driving their cars slowly to look for an empty
parking space in a parking lot for sure because
most people already know and even book the
parking spaces they need.
8. Smart irrigation system using IoT
• Just like mentioned earlier, IoT can be implemented in
many works, even the significant ones.
• An example of a significant work that can be
automated by utilizing IoT is irrigation system that is
called smart irrigation system using IoT.
• Well, in fact, the term irrigation itself has a broad range
of instances.
• Anything that involves watering an area regardless of
whether the area is small or large is called irrigation.
9. Contd..
• So, watering our front yard can be considered as irrigation and
watering a several-acre rice field is also considered as irrigation.
• However, no matter how large the size of the area that needs to be
watered is, irrigation can really take some time.
• Based on that, a smart irrigation system was invented by utilizing
IoT.
• This system allows us to set when the irrigation will take place and
to control the process remotely.
• So, with this system, performing irrigation can turn into a fun
activity because we can do it while doing other activities.
• This of course really saves people from the trouble of wasting their
time to irrigate their own front and back yards.
11. Automated street lighting using IoT
• It has been mentioned earlier as well that there are insignificant
works that can be done using IoT and one of which is turning street
lights on and off.
• Well, although this work seems to be an insignificant work, it can in
fact be a significant work if the number of lights is significant or the
street is quite long.
• Decades or even centuries ago, people lighted off street lights
manually, so that a profession for people that requires them to turn
on and off street lights was quite common back then.
• However, after light sensor was invented and street lights started to
turn on and off automatically, such profession started to fade.
12. Contd..
• Moreover, now those street lights can even be
monitored and turned on and off remotely
using IoT and of course, they still maintain
their ability to automatically turn on and off
by sensing certain amounts of sunlight.
• This system is really helpful in big and smart
cities that really need to conserve energy.
13. Smart healthcare system using IoT
• Another utilization of IoT in daily life that has
become quite popular in recent years in its
utilization in a healthcare system called smart
healthcare system.
• As you have known, health has always been
one of the most important aspects in our life
since the first human stepped on earth.
14. Contd..
• So, people have always been trying to look for better
ways to provide health services and this time, it is IoT
that contributes to the world of health.
• There are many things in healthcare that can be made
easier by using IoT, such as patient monitoring and
medical equipment monitoring.
• By using IoT, healthcare professionals can keep in touch
with their patients anywhere and anytime.
• So, if the patients forget about their treatment
schedules, the healthcare professionals can remind
them, saving them from any unwanted risks.
15. Contd..
• Another example of utilization of IoT in the
smart healthcare system is medical equipment
monitoring.
• Maybe, patients do not notice about the
difficulty in finding available equipment
needed by the patients, but healthcare
professionals know the difficulty very well.
16. Contd..
• There are many times that they need to spend so much time in
order to find the medical equipment needed by the patients
entrusted to them, such as wheelchairs, connected inhalers, and
many monitoring devices like heart-rate monitoring device, glucose
monitoring device, mood monitoring device, and so on.
• With IoT, healthcare professionals will be able to know the
availability and the location of the needed equipment in no time, so
that their patients will not have to wait too long to get the
equipment.
• Those are some examples of utilization of Internet of Things or IoT
in our daily life.
• Although IoT still and will always have security issue, it is still worth
to use, especially because the issue tends to rarely happen.
