Measuring Water Level With Ultrasonic Sensor: 7 Steps

We soldered wires to ultrasonic sensor (we used FTP or UTP cable; it can be one of them). Then we installed sensor in small custom made housing from acrylic glass.

Ultrasonic transducer - Wikipedia

Ultrasonic transducers or ultrasonic sensors are a type of acoustic sensor divided into three broad categories: transmitters, receivers and transceivers. Transmitters convert electrical signals into ultrasound, receivers convert ultrasound into electrical signals, and transceivers can both transmit and receive ultrasound.

Ultrasound - Wikipedia

Ultrasound is defined by the American National Standards Institute as "sound at frequencies greater than 20 kHz". In air at atmospheric pressure ultrasonic waves have wavelengths of 1.9 cm or less.

LESSON 17: Measuring the Speed of Sound with Arduino and ...

Thank you very very much for your lesson Mr. Walter what i am thinking that if we can measure the speed of sound so with this same little sensor we can measure the temperature in air as the time in microseconds is know and we also know the distance in air on different temperatures, if we set ultrasonic sensor in very precise known distance ..
