The ultrasonic transmitter in the aerodrome will transmit the signals in the 360-degree circle these signals will reflect back to the receiver when any object or person comes on transmitting line. This ultrasonic sensor we are rotating in 360 degree angle continuously and monitoring the output of the sensor. !t any time if there is any object or person entering in to the area we are indicating by using a bu""er and at the same time we are passing this information to the control room with #$ transmitter. In an ultrasonic intrusion detection system a constant high fre%uency acoustic signal is transmitted by a group of transducers. The ultrasound waves flood the protected area. #eceiving transducers monitor the ultrasound reflected by objects in the protected "one. If anything moves it produces a change in the phase of some of the reflected waves. This phase change is detected by sensitive electronic circuits using a controller. To develop this system we are using &0'( controller along with #$ modules. This system can be used to identify intrusion not only for border areas at the same time for research centers prohibited areas and so on. )ltrasonic sensors *also known as transceivers when they both send and receive+ work on a principle similar to radar or sonar which evaluate attributes of a target by interpreting the echoes from radio or sound waves respectively. )ltrasonic www.svsembedded.com SVSEMBEDDED
