Frequently asked questions
How do I drive it with an Arduino?
The transmitter needs a 25 kHz square-wave signal, which a microcontroller timer can generate through a driver circuit. The received echo usually needs an amplifier before the microcontroller reads it.
Can the same transducer send and receive?
It is normally used in pairs, one for sending and one for receiving. A single-transducer design needs switching circuitry.
