    We used this initially as a distance meter on a robot based on a Raspberry Pi. It worked as designed, but had one problem with it : when the distance became too big, the echo pin stayed high. We are unsure this had something to do with the 5V-3.3V level convertor we had in between the HC-SR04 and the RPi . We worked around this limitation with an IR ... Read more

    Funciona perfectamente con las placas arduino originales sin embargo la única pega es que no es muy exacto pero cuando lo vas a comprar y sabiendo su precio sabes que no es de muy alta calidad pero esta bien para pequeños Proyectos y para darte una orientación de la distancia a medir. Facil instalación. Read more
