The network and communication
of digital, mechanical and electronic devices is known as IOT or internet of
things. In IOT, device-to-device communication is done. While on the internet
there is another type of communication going on like people-to-device and
device-to-people. IOT is a new technology first revealed in 1999 by Kevin
IOT is used for ease of our
lives and to save time. IOT plays important role in health care, marketing,
farming, industrial development, transportation, weather notification, machine
learning, pollution control, road safety, controlling temperature, home
security, managing appliances, etc.
Suppose you are driving a car
and there is an accident on the road. Your car sensor will detect the accident
and send a message to the ambulance and police department. The ambulance has a detection
system also which is connected to the internet. So all process will be
automatically done between car devices and ambulance device. This will save
people life and time also.
Room AC has a detection
system that can count a number of people in the room and it can adjust the
temperature accordingly. If there is no person in the room then AC will be
turned off automatically. This will save your electricity bills. According to research
if all the digital devices in the United States will become part of IOT then it
saves $300 billion annually.
Wearable devices check your
blood pressure and heartbeat and notify you about a health problem. Wearable devices
can also send an automatic message to your doctor about your heart problem. So you
can be treated by the doctor before the heart attack comes.
In your home, all the digital
devices including coffee maker, toaster, AC, windows, doors, light bulbs, and
heater are connected with each other through a data hub. All these devices are
connected with your wearable device, smartphone and computer. If you wake up in
the morning then your wearable device detects your wakeup time and sends
message to toaster and coffeemaker. Your coffee and bread will be ready without
If you have a digital home
and there is no one in the home then sensors will automatically close home
windows and garage gate. If you are living in a digital city then people behavior
will be calculated via devices and it will ease your life. For example, your
car will notify you if there is high traffic on the road and it will direct you
to another road.
Digital devices are also used
to detect fire in the forest and detect an increase in pollution. All these
types of devices communicates with each other and provide safety to the people
and animals. You can also attach a digital device to your cat or dog and you
can measure the location or behavior of your animal through a smartphone or
As all the digital devices in
the IOT are connected via the internet so there are high chances that your data
can be accessed by the hackers. Some device manufacturers also make hidden
features in the device that collects data from the device and send to the
company. The company then sale your data to a 3rd party.
