Abstract
Many areas of the world suffer from geological disorders. Disasters are impossible to prevent and causes destruction to both environment and human resources. Naturally occurring disasters like earthquake, floods, etc. can cause massive destruction and sometimes lives are 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 harder. The proposed system provides a human detection quad-copter which might detect alive humans in debris in order that timely help can be made available to the victims. The alive individual detection system contains Passive Infrared sensor (PIR) which provides the information about the presence of alive human body. Radio Frequency Technology is used to control the quad-copter. Flight controller used in quad-copter is the main functioning body of the aircraft. It is a circuit board that receives different commands sent by user to control speed of motors so that quad-copter could be stable in fly mode. Electronic speed controller receives command from microcontroller and further gives command to the motors for rotation. The instructions given by transmitter are received by a radio receiver connected to flight controller. ATMEGA8A microcontroller is used to 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 right time. This technique is additionally user friendly, economical, semi-autonomous and efficient for detection.
