I.INTRODUCTION
Many watchmen had been suffering due to the vital injuries which
are being unnoticed and many are forced to move to the faraway places without knowing their exact locations. Large number of
people serving in many vast places suffers in many attacks and various health issues that worsen their conditions. This project proves to be very efficient for the watchman to overcome the hardships. One of the objectives of this paper is to use a SOS facility which can sense such situations and alerts the nearby people for obtaining help. The sensors are designed in the manner that they are used as a wearable device. The methods of combining of the different sensors must not collide or affect the performance of the other sensors in the working. Sensors will pick up the vital signs from the watchman and the status of the watchman and position are shared through a secured WIFI communication. If no
nodes are nearby to connect, the watchman is directed towards the objective or in worst case if the watchman is wounded, he/she is
directed towards the nearest safe hospitalizing place. This helps them to work in an efficient manner. The GPS sensor provides the exact location of the person moving so that the person can be detected easily and given treatment. Securities working in the houses need to be in good health conditions and provided with the relative tools so that they can protect the people. If they are attacked by the theives or any other people, they may press the SOS button
to acknowledge the people and others to safeguard themselves. In Today’s world, Security is the major concern for the people. So,
the people are working in job like Watchman, Security needed to
provide the safety of the person and their products. During their
working, they need to be in a healthy body condition to accomplish their tasks. In order to analysis their condition and health, it is necessary to provide them with the strap built with sensor. At any
circumstances for any person this strap can be helpful. Starting
from person who is working inside a separate room to the person
who is in the road, it can be used.
For example, a person seems to be lying in this chair in the sleeping position, his friend considered him as sleeping after sometimes in the purpose of awaking him he touched his hand.
Later found out that he died, in front of him his friend was dying
but he couldn’t acknowledge it. Life has changed in the manner with the various development but the health of the people can’t be judged anytime. No one can judge the time and things happening around all of the sudden things are changed. It is our life we need to survive for the people who we love and care for us. We need to always protect us with all the safety measures that are capable for us. In that way the strap can be helpful for all the people to know about their body part condition.

Methodology is way of defining the selective method used for
the working and modulating the components in a effective manner. The ways in which the process of the work can be easily modulated. Placement and Calibration of the sensors for different individuals. Providing Strap in a weightless manner for wearing. Attaching all the sensors in the strap coat. Sensor will pick up the vital signs from the watchman and the status of the watchman and position are shared through a dedicated WIFI connection. When the SOS button is pressed the concerned people are alerted and the whole place is saved form possible major attacks. After the attack, there may be many chance for their survival of the injured person. There are many minor injuries which could cause the person to death if not noticed within the time.
2.1 Essential Devices The following are the components used: ➢ Node MCU
➢ Pulse rate sensor
➢ Temperature sensor
➢ Arduino
➢ GPS sensor
➢ Wires
Node MCU (microcontroller unit) is an source components of hardware and software development in the environment for the interconnection of all the functionalities in
the combination of the sensors. It acts as an intermediate with
all the different sensors correlating in an effective manner for
obtaining the specified output. Pulse Rate Sensor is a sensor used to measure the blood
pressure of the person. It can be fitted with microcontroller to
gather some power supply for its working. It can be designed
in the format that the readings are obtained without any
intermediate disturbances. The blood flow is more important for the person for his/her survival. Heart transmits the blood to
the body parts in the defined flow of energy. The flow of blood
can indicate the person is good in health. Temperature Sensor is a mode of sensor used to measure the temperature of the body parts of the person. Body
Temperature is the main source of the indication that progress on the condition of the body. It helps us to indicate that the person is absolutely normal and healthy. The sensor can be available in many different forms for obtaining reading. It can fitted in the coat in the manner that it not disturb the other sensors. Fig 2.2 Coordinate device

GPS sensor is the important component used in the process of detecting the location and tracking it. It can be helpful in the easy access of the person in the global world.
This gives the accurate place of the person who is wearing it.
It requires only less amount of the energy in the working
process. Vast areas can also be accessible from the place we need. Using the GPS connected with the Arduino, the working
can be compactible. It requires only less cost. Fig 2.3 GPS with arduino SOS is a signal or helpline which indicates to others that you are in danger and require help quickly. Survivor Outreach Services (SOS) is an Army program where services are provided through each component, Active Duty, National Guard and the Army Reserve, based on assigned counties within designated state and territories. The Army Reserve assigned counties and territories coverage services have been supported through an Army Reserve contract. The Army
Reserve has regionalized Family Programs to include the SOS program. The Readiness Divisions and the 9th Mission
Support Command will provide Survivor Outreach Services utilizing government personnel assigned to each of the seventeen assigned coverage areas. It send the help request to the person who are being
able to get the frequent reading of the person. The person who
is able to monitor the sensor reading get the notification of
“HELP” from the person in danger The below diagram explains the sensors being fitted
in the coat Fig 2.4 GPS sensor in coat 2.2 Algorithm Fig 2.5 Using of SOS facility International Journal of Engineering Research & Technology (IJERT)

The working of the GPS sensor with SOS is as follows:
➢ If the SOS button is pressed and after sometime signal
is not available, then it means that communication
between supervisor and sensor is notestablished.
• The supervisor now monitors the lastplace
where the location shared through GPS
• But if thecommunication is not established
even after sometime, then a message
‘HELP’ will be sent to the emergency
contact.
➢ There are only two possible waysused:
• The person is in normalcondition
• The supervisor doesn’t receive any
signal but he can monitor him.
• And after few more times, tokeep
monitoring to see if any change has
occurred. If no change continues
monitoring.
• The person is in abnormalcondition
• If any illness isdetected,
• Sensor transmits a message to
the supervisor end and the
GPS will share the location at
thesupervisor end.
• The supervisor will send an
emergency messageto the
terminalcontact.
• If any problem is notdetected,
• There are two possible reasons
for this:
• GPS failure
• Sensor out of range
• Twoconditionoccurs
emergency message will be
sent to the terminal contact
via the supervisor.

health monitoring kits accessable within the short period
to reduce the person from entering into the critical condition.
Large number of defects and diseases inside the human body
get unnoticed at the first stage of the diseases occurance stages. In later stages it may result in loss of life and person
who got affected may result in the transfer of any
communicable infections to all other people around the surrounding environment. This problem can be controlled to
maximum stages and lose of the life can be prevented.
This method can be used in security person as well as the working person include drivers (who health is important all the people life travelling in the public transport are depend
on him) and scientists or lab workers carrying chemical substances, person at the electrical works etc. More we develop in the field of technology, higher the range of security needed and it may also result in the some harmful affects to
the human body. No one can sure about the things happening
in the future but we can prevent ourselves or take some precautions for the upcoming challenges.
