Ultrasonic RADAR

2. Description Arduino UNO is Brain of this Project.
Ultrasonic RADAR consist of few Components like HC- SR04(Ultrasonic Sensor), SG-90(Servo motor), 16X2 LCD.
Ultrasonic RADAR displays Polar Coordinates of Object(s) on LCD.
Servo motor is responsible for 180° clockwise and Anti-Clockwise Rotation.
Ultrasonic Sensor measures distance of object from it.

4. Working
Ultrasonic RADAR works by measuring distance with Ultrasonic Module and angle by servo motor’s feedback system.
Ultrasonic Sensor first emits a burst of ultrasonic soundwave and then this soundwave reflects back from object and piezo crystal in Ultrasonic Module receives it and by measuring time between arrival and departure of soundwave we can measure distance between object and Ultrasonic sensor.
Arduino UNO calculates Distances and angles and print it on 16X2 LCD.

5. Applications Used to measure the obstacle distance.
This system used in automotive parking sensors and obstacle warning systems.
Used in terrain monitoring robots.
Military surveillance.
Meteorologists use radars to track storms
