Ultrasonic Radar Using PC Via USB

Objective

·        To detect objects within the vicinity of a small area or room

·        To rotate the sensor continuously 360 degrees

·        To use an electro-mechanical device to rotate the ultrasonic sensor without twisting its wires

·        To determine what the angle of the motor is

·        To use a microcontroller for distance measurement and motor control

·        To design an appropriate electronic circuit in order to achieve all the above

·        To program the microcontroller using C language

·        To send the data to the computer via USB

·        To create a graphical user interface using LabVIEW programming

·        To display a Radar display with all the objects detected

Project description:

The aim of this project was to design and implement a Radar system for detection of objects within the vicinity using an ultrasonic range sensor. The sensor needed to be mounted on a rotary shaft in order to scan the area 360 degrees at a suitable (Radar) speed. A Microcontroller was used to control the motor, get the range from the sensor, process the data and send it to the PC via USB. The data needed to be displayed on a PC in real time as a Radar display by plotting the distance of the objects vs the angle of the motor.
