I have adjusted this code multiple ways and think I am missing something easy. I want the code to light up an LED when it is with n a certain distance. WebDec 30, 2013 · The short answer is "no, a sonic range sensor can't do it". It might "work" under very controlled conditions, but relying on only the attenuation of the returned signal to determine thickness may leave you open to incorrect results due to multipath propagation effects.. The more traditional way to measure thickness with sound is called profiling.

WebThe HC-SR04 ultrasonic sensor uses sonar to determine the distance to an object. This sensor reads from 2cm to 400cm (0.8inch to 157inch) with an accuracy of 0.3cm (0.1inches), which is good for most hobbyist projects. In addition, this particular module comes with ultrasonic transmitter and receiver modules.

WebHello, In this tutorial I am going to show you how to 1. Connect the HC-SR04 to an arduino and print the distance to the serial monitor, 2. Connect an LCD and print the results there instead. The sensor works by pinging out an ultrasonic sound we cannot hear. It then starts a timer and measures how long it takes to get that ping back.
