Howdy! I got a couple of these to try out as a front mounted range sensor with a cube.
Does anyone have experience integrating them? I have it displaying distance, but it’s very off and I can’t seem to find a scaling value that makes it better.

I played with one of the Sharp models a few years ago.
You need to use a capacitor between 5v and ground to reduce noise, as it uses the 5v input as Vref - any noise on the power results in an inaccurate signal.
I should add that ultimately I gave up, but we didn’t have avoidance back then. It’s probably more suited to avoidance than an altitude source.
Also the analog signal is “backwards”, so they aren’t plug and play alternatives to an analog sonar.
By that I mean the analog signal decreases with range, not increases as you might expect (and as the maxbotix sonars do).
