3. ABSTRACT
Many areas of the world get affected by natural calamity. Disasters are unstoppable and
leave behind a great loss of life. Disasters like floods, etc. Cause mass destruction and
often lives get buried or trapped in debris. In such situations detection by rescue
workers becomes time consuming and due to the vast area that gets affected it becomes
more difficult. In this system, we are proposing a human detection quad-copter which
can detect alive humans in debris so that timely help can be made available to the
victims. The proposed alive human being detection system contains Passive infrared
sensor (PIR) which gives the information about the presence of alive human body.
Radio Frequency Technology is used to control the quad-copter. ATMEGA8A
microcontroller will give an alerting message to the rescue operator of the affected sites
and they will give proper rescue to the affected victims. In disaster sites, it will be a
great help to rescuers in detection of more alive human beings at the proper time. This
system is also user friendly, economical, semi-autonomous and efficient for detection.

4. INTRODUCTION
A timely rescue can only save the people who are buried ad wounded due to a disaster. I such
situations, rescue system must take fast decisions under pressure, and try to get victims to safe
location at their own risk. The rescue system must collect the location information and status of
victims as quickly as possible so that medication and fire-fighters can enter the disaster-prone area
and save people. All these works are performed mostly in very dangerous and risky situations by
human and trained dogs. Detection by rescue workers becomes time consuming and due to the
vast area, that gets affected it becomes more difficult. The project proposes a drone or quad-copter
that fly in a disastrous area and helps in identifying the live people and rescue operations. A
Passive Infrared sensor is used in the project which emits infrared rays to detect humans. As live
human body emits thermal radiation it is received and manipulated by the PIR sensor to detect
humans. Once the people are located it immediately gives audio alert to the authorities so that help
can reach the live person very fast. This PIR sensor is placed on a moving all direction quad-
copter that can fly in the earthquake prone areas. The quad-copter is driven on a brushless dc
motor for increased torque. Detection by rescue workers is time consuming; therefore, here we are
using the quad-copter for earthquake rescue operation.

5. OBJECTIVIES
 To detect humans in the disaster areas by the help of drone.
 The information of the alive humans in the affected site will be sent as a
message to the rescue operator.
 They will give proper rescue to the affected victims.
 It will help to save more humans at the proper time.

6. COMPONENTS
 PIR Sensor (Human Detector)
 Fire Sensor
 Gas Sensor
 GSM Module
 WiFi Module
 LCD Display
 Arduino Mega

7. PAYLOADS
PIR SENSOR
 Passive Infrared sensor can be used to presence of human being its proximity . A
PIR sensor detects the infrared light radiated by a warm object.
 In detects a human being moving around within approximately 10m from the
sensor. This is an average value as the actual detection range is between 5m to
12m.
APPLICATIONS OF PIR SENSORS
 All outdoor lights
 Lift Lobby
 Multi Apartment Complexes
 Common staircases
 Shopping Malls

8. FIRE SENSOR
 The fire sensor is used to detect fire flames
 The module makes use of fire sensor and comparator to detect fire upto range of
1m.
 Input voltage +5v DC

9. GAS SENSOR
 A gas sensor is a device which detects the presence or concentration of gases in
the atmosphere.
The gas sensor module basically consists of 4 terminals;
 Vcc
 GND
 Digital Output
 Analog Output

10. APPLICATION OF GAS SENSOR
 Used in industries to monitor the concentration of the toxic gases.
 Used in households to detect an emergency incidents.
 Used at oil rig locations to monitor the concentration of the gases those are
released.
 Used in air quality check at office.
 Used in air conditioners to monitor the CO2 levels.
 Used in detecting fire.
 Used to check concentration of gases in mines.
 Breath analyzer.

11. GSM MODULE
 A GSM module or a GPRS module is a chip or circuit that be used to establish
communication between a mobile device or a computing machine and a GSM.

12. WIFI MODULE
 The ESP8266 Wi-Fi module is capable of either hosting an application or
offloading all Wi-Fi networking functions from another application processor.

13. ARDUINO MEGA
 The Arduino mega is a microcontroller board based on the ATmega. It has 54
digital input/output pins, 16 analog inputs, 4 UARTs a 16 MHz crystal oscillator
a USB connection, a power jack an ICSP header, and a reset button.
 It contains everything needed to support the microcontroller simply connect it to
a computer with a USB cable or power it with a AC- to –DC adapter or battery
to get started.

16. CONCLUSION
 In order to similar the Quad-copter a remote was designed and the control was with
rescue team. This helped the rescuers to move the quad-copter in various directions.
This quad-copter consists of a PIR-sensor and a camera fitted to it and when the
sensor detects the alive human beings, it will produce the sound. Among the few
keys two are used to move this quad-copter in forward backward upward and
downward direction and other two are used to move in left right and around 360
degrees. The PIR sensor triggers and starts sensing. The PIR detection angle is 120
degrees around it. By additional with the drone the gas sensor is fixed to measure
the leakage of the gas and fire sensor to detect the fire in that area.
