Abstract – IOT(Internet of Things) is the popular
technology which consists of embedded system with sensors,
actuators and network connectivity. IOT is helpful in sensing
and controlling the existing infrastructure, creating
opportunities for enhancement of upgrading future. With the
help of sensors and actuators, the IoT plays an important role
in various fields like education, medical, agriculture, military,
etc. It can easily integrated into systems developed to facilitate
everyday life. In this study; the system is developed to
calculate indoor oxygen content. With the help of these
measures of oxygen the system is able to rescue the person
who trapped in closed area. Moreover, this system reads the
amount of oxygen in surrounding environment with the help
of sensors and able to calculate average life span of people
until he/she gets free, as well as system can check the
threshold values of levels of oxygen to predict the life span of
the people. To implement this, system uses various sensors
such as humidity, temperature and oxygen sensors to measures
the corresponding values with respect to surrounding
environment.
Key Words: IoT, embedded system, sensors, temperature,
agriculture, life span, humidity.
I. Introduction
IoT is a giant network which is connected devices. These
devices gather and share about how they are used and the
environment in which they are operated. It’s all done using
sensors. sensors are embedded in every physical device. It
can be your mobile phone, electrical appliances, Pecos
barcode sensors, traffic lights and almost everything that
you come across in day to day life. These sensors
continuously emit data about working state of the devices.
Even though these hardware and software, which are often
used to facilitate human life and to make the work done by
human power machine, are systems that can stimulate and
interfere with human life to save and to perceive possible
harm . In this project, the remaining life expectancy of
people who are left behind in an environment without
oxygen entry can be calculated and informed to both the
screen and outside accessible environments. A person who
is left behind does not know the remaining life span and
thinks that the air will be consumed immediately, especially
for those who are claustrophobia, this effect is much more
and affects the amount of oxygen in the environment
negatively. As a result, people are affected psychologically
or physically such as rapid breathing or self-harm by
panic, and even those who can survive as a result of
these effects die prematurely. With this improved
system, it is ensured that the person staying indoors is able
to see the time remaining momentarily, to live for the period
of time under control, to avoid unnecessary panic
awareness and to avoid movements that will adversely
affect the amount of oxygen in the environment. At the
same time, in sudden oxygen drops, both the person staying
in the closed area and the user outside are warned; it is
necessary to stay stable and thus the survival time can be
extended.
