Ultrasonic Based Radar System Project Using 8051
We
come across situations where we need to keep a watch over prohibited areas to
avoid trespassing. Now keeping human labor for this purpose is costly and also
not reliable for keeping a watch over an area 24×7. So for this purpose
ultrasonic radar project for unauthorized human / animal or object detection
system. The system can monitor an area of limited range and alerts authorities
with a buzzer as an alarm. For this purpose we use a microcontroller circuit
that is connected to a ultrasonic sensor mounted on a servo motor for
monitoring.
We
also interface a buzzer and LCD screen for monitoring the detection status. The
radar keeps monitoring the environment checking the ultrasonic sensor echo. As
soon as an object is detected the data of detection is processed and sent to
authorities with an alert of where exactly the object was detected. Thus
ultrasonic radar proves to be a very useful system for 24×7 monitoring of a
particular area/region.

Ultrasonic
Radar system Project Ultrasonic Module acts as an input device and servo motor
acts as an output device and servo motor is rotated at 180 degree by the
microcontroller. Ultrasonic radar System ultrasonic sensor detect any object in
the range it detects it and send the data to the microcontroller.
The
microcontroller then process the data and decide whether it is range of 25 cm
as we have kept the distance of 25cm for this project that any object in the distance
of 25cm will be shown in the LCD . And if the object is in the range the
message will be shown in the LCD with the accurate distance of the object with
the angle in which the object is there and the message will be displayed on the
LCD and servo motor is use to rotate the radar at 180 clockwise anticlockwise
simultaneously the buzzer starts ringing with flashing the red light as sign
that the object is been detected.
