Hi everybody,I'm trying to do my project about : "Measure long distance using ultrasonic sensor" and the desired distance is at least 10m ( 10m-20m) and I don't know how to design because it's a long range if using ultrasonic sensor. I searched much and still now I can't find a transducer or a sensor can satisfy. Can you introduce to me a diagram and a circuit? My deadline is nearly.Thanks you very much.
