Mini IR Radar For Unauthorized Object Detection Project

Download Project Document/Synopsis

Radar’s are used on airports as well as military bases for unauthorized object detection. Radars work on the principal of echo detection in order to detect objects. In air the refection of echo waves is measured on the basis of time taken to receive the signal. Based on this data the object distance is identified. We propose to simulate this concept using Infrared technology. Our system consists of a IR sensor radar that rotates constantly at 360 degrees. The radar constantly emits IR rays and measures reflection. On detecting reflection from any object within its range the radar stops and sends a signal. The radar also sends the angle at which the object was identified. We here use a small IR transmitter receiver pair. The pair is interfaced with microcontroller to control the circuit working. The microcontroller constantly receives the radar input. On sensing an object the radar sends an alert message to the microcontroller. The microcontroller now gets the data and also gets the radar direction in order to get angle at which object was detected.
