Distance
The ultrasonic sensor sends out high frequency sound waves in the environment of the detection,
meanwhile receives the reflection of the ultrasonic echo from nearby objects and directly outputs
distance reading through processing the echo time . Due to waterproof ultrasonic transducers it can
be used i.e. water tanks to verify water level or gasoline tanks.
