Ultrasonic module

All About -
The Ultrasonic module uses 20KHz ultrasonic waves, which cannot be
heard by people.
It calculates distance by measuring the time required for these waves to
return to the module after being reflected by an object.

Measurable range
*The Ultrasonic module measures the perpendicular distance to an object. The ultrasonic
waves are radial, and not linear. If any obstacle within the radial range of the measurement
interrupts the measurement, an error may occur.
*If an object is too small to detect, it would be difficult to obtain a precise measurement.
