ABSTRACTABSTRACTThe 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.

PASSIVE INFRARED SENSOR (PIR):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.

DESCRIPTION: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.

Cont..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.

Cont..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.
