    Pros: It can measure distance. I have measured up to 3 meters! Good tutorials online, compatible with arduino. Cons: none. Funny device, put it under your butt when you squat to see how low you go each time. I can recommend it Read more

    Pequeño y funcional sensor de distancia para Arduino u otros microcontroladores. Aunque se especifíca que funciona a 5V, también trabaja con 3V3, aunque no con el mismo rango. Medidas bastante precisas, con un margen de error de unos 2~3 cm. Pros: Pequeño tamaño, sencillez de uso y conexión. Cons: Por ... Read more

    Works great with Arduino and other microcontrollers, has a nice accuracy for flat objects, senses curved objects as well but not so accurately. The price beats all other offers of similar products. Longer range than IR rangefinders, just the perfect thing you want to strap on your robot to give it some ... Read more

    Ordered 2 where the first was DOA. Considering the price a RMA is waiste of everybodys time. The other that works, does what it is supposed to. Nice build and lot of tutorial on the net for the device. Old Construction, since the newer can do the same on one speaker. Like it and will probably order more,... Read more

    Pros: Works absolutely perfect for being so cheap. The one I have measures accurately up to around 1.5m. On the close range it works until around 0.5cm, which is great! It was very easy to get working as well, just plugged it in, followed the tutorial and it worked the first time with my Arduino without ... Read more

    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 ... Read more
