ultrasonic distance sensor
Ultrasonic distance sensor: This device, a somewhat complex piece of technology, uses ultrasonic sound waves to determine the physical length between it and an object from which said echoes return. The main tasks of the sensor are accurate distance measurement, obstacle detection and liquid level sensing. This sensor is not just a breakthrough in engineering, it quenches the technological thirst with features like portability & light-weightedness, high accuracy and wide measurement range — hence can serve for an extensive number of environments. It emits a pulse of ultrasonic sound and waits for the echo to return, calculating distance based on that time interval. The echoes are then turned into a distance measurement. It is used in everything from automotive parking assistance systems, to industrial automation and even robotics.
