Copy of std Ultrasonic range, but returns Max distance on failure so we can assume nothing close to us. My sensor seems to go low on ping capture, not success, so I changed timeout to max round trip to get full range.
To use the nodes in your project you should have the gweimer/hc-sr04-ultrasonic library installed. Use the “File → Add Library” menu item in XOD IDE if you don’t have it yet. See Using libraries for more info.
