This watch uses sensors to monitor a wearer's pulse and allows them to send distress signals. It works by:
1. Military personnel and crew members wear the watch, which contains a pulse sensor to detect the wearer's heartbeat.
2. If in danger, the wearer can press a button to send an alert signal along with their pulse reading and voice message.
3. The signal is sent to a microcontroller and then to other watches, allowing for rescue if the wearer's pulse confirms it is actually them in distress. Additional sensors and encryption protect against improper watch use or signal interception.
3. GUARD WATCH
▫ All the crew members and
the commando wear the
watch.
▫ Using heart beat
recognizer, the pulse of the
military man is
checked and gets
activated.

4. PULSE RATE SENSOR
4
Pulse sensor fits over a fingertip and
uses the amount of infrared light
reflected by the blood circulating inside
to do just that. ... When the heart
pumps, blood pressure rises sharply,
and so does the amount of infrared
light from the emitter that gets
reflected back to the detector.

• The watch is to be worn by all the crew
members and the commando.
• When the person(military man)is in
danger,the danger button in the watch is to
be pressed.
• Then that signal along with the voice
message of the man is sent.
• So that the person can be saved.
7. 7
This is done by following:
• When the person press the danger button that
signal along with the signal from heart beat sensor will
be sent to the microcontroller.Then it will be sent to all the crew
members.
• Here the watch gets activated only if there is a pulse in
the heart.
• So that only pulse rate sensors are used.
• The voice recogniser is used to verify whether the voice
belongs to that particular member or not.
• If that voice doesnot belong to him then the watch gets
deactivated.So that we can avoid the watch usage of someother
person in the case of missing of watch.All the messages are encrypted so that
the intruders cannot track the information.
8. WEARABLE GLOVES
• Recognises the gestures
▫ of the Military man and
▫ send the Corresponding
▫ code to all the crew
▫ Members.

10. PROBLEM STATEMENT
During break hours students find difficult to locate the
faculty around the college and department.
A mechanism has to be designed so that the last seen
location of the faculty must be updated to the students, so
that they can easily locate them.
11. OBJECTIVE
11
We suggest to use RFID tags and readers
to find the location of the faculty and report
the location to the students
13. 13
It consists of three components
RFID TAG
RFID READER
MICROCONTROLLER
RFID SYSTEM
14. Consists of an integrated circuit and an antenna
Composed of a protective material that holds the pieces
together and shields them from various environmental
conditions
There are two types of tags
Active
Passive
Active RFID tags have an on-board power supply
Passive tags must be “powered up” by the RFID reader
before they can transmit data.
RFID TAG
15. It consists of a scanner with antennas to transmit and
receive signals and is responsible for communication
with the tag and receives the information from the tag.
