    Hello,

    A group of high school students is working on a project which involves using
    ultrasonic sensors to measure small distances (around 6 to 60 inches).

    There are a large number of possible transducers / sensors.

    Anybody have any experience and can suggest a source of circuit ideas for
    them to experiment with?

    Thanks
    Ed.
