Ultrasonic Rangefinder Application:
An ultrasonic range finder sensor enables a robot to detect obstacles in its path by utilizing the propagation of high-frequency sound waves. The sensor emits a frequency sound wave, which bounces off a reflective surface and returns to the sensor. Then, using the amount of time it takes for the wave to return to the sensor, the distance to the object can be computed. To increase the sensing range, the sensor can be mounted to a servo to allow it to rotate.
