Using Arduino Sensors
1

Hello I'm Inov
I want to measure the distance from the air into water with Arduino Uno and it connected by ultrasonic sensor. The distance from air into water is 10-15 meters.
Is there any type of ultrasonic sensor that I can use for it? If there is, what kind of ultrasonic sensor? and how the specification of the sensor?

thank you
