Alive Human Detector Robot In War Fields Using PIR Sensors

-



        
Abstract: Now-a-days, Automated systems have less manual operations, flexibility, reliability and accurate. Due to this demand every field prefers automated control systems. Especially in the field of electronics automated systems are giving good performance. In the present scenario of war situations, unmanned systems plays very important role to minimize human losses. The objective of the project is finding out a injured person or person caught in a battle field using PIR for rescue operation. If an injured person or some detected it can be informed using a wireless technology using RF.

Operation :

        The system requires PIR sensor, Wireless RF camera. Passive Infrared sensor (PIR sensor) is an electronic device that Measures infrared (IR) light radiating from objects in its field of view. PIR sensors are often used in the construction of PIR-based motion detector. Apparent motion is detected when an infrared source with one Temperature, such as a human, passes in front of an infrared source with another temperature, such as a wall. By using RF Technique we can control the movement of vehicle in the Specified direction.
       
          In receiver section controller is used to receive the Encoded message and Decode the message accordingly the vehicle is controlled. All objects emit what is known as black body radiation. It is usually infrared radiation that is invisible to the human eye but can be detected by electronic devices designed for such a purpose. The term passive in this instance means that the PIR device does not emit an infrared beam but passively accepts incoming infrared radiation

Abstract:             Temperature maintenance is the prime consideration for the effective and safe handling of the patient. Mistakes regarding to it can lead to life-threatening condition for the patient. The normal body temperature of human is 37.5 deg. Celsius. The blood from blood bank is at lower temperature.It is dangerous to directly infuse cool blood in patient.
