    I used a few of these in arduino project and they work flawlessly with example code available from arduino. Very good price and I get centimeter level accuracy on measurements and close distances (10-30cm). On longer distances (2m) it still gives reliable results.

    Permite una configuración sencilla y una detección de distancia bastante acertada. Pros: -Fácil configuración -Buen desempeño Contra: - Quizá un poco de ruido en la lectura, pero nada grave

    It worked wonderful, was easy to use with the libraries that can be found all around the web. However, when I tried to take it apart (wanted to put the receiver away from sender), it short circuited. It would have been nice if this was possible, but for this price it's still a great product.
