Radars are used at airports as well as military bases for detection of unauthorized objects. Radars work on the principle of echo detection to detect objects. In the air the reflection of the echo waves is measured on the basis of the time it takes to receive the signal. Based on these data the distance of the object is identified. We intend to simulate this concept using infrared technology. Our system consists of an IR radar sensor that rotates constantly at 360 degrees. The radar constantly emits IR rays and measures reflection. Upon detecting the reflection of any object within its range, the radar stops and sends a signal. The radar also sends the angle at which the object was identified. Here we use a small pair of IR transmitter receivers. The pair is interconnected with the microcontroller to control the operation of the circuit. The microcontroller constantly receives the input of the radar. Upon detecting an object, the radar sends an alert message to the microcontroller. The microcontroller now obtains the data and also obtains the radar address to obtain the angle at which the object was detected.
It can be understood in the following video:
