Support Seed Grove Ultrasonic Ranger

[Former user]

Hi,

thanks for this library. Unfortunately it does not fully support the Seed Grove Ultrasonic Ranger Sensor. This sensor uses only one pin.

Sometimes I got some values back, but most of the time the values returned were 0. The ratio is nearly 1 successful attempt in 10 tries. I tried to debug the issue, but could not solve it. It steps out on this line

Do you have an idea why this is the case? Are you planning to support it?

Best regards, Andreas

It's not on the supported list and I don't have the sensor so there's little I can do. There's settings in the library that can be used to increase timeouts that may cause it to work. If that doesn't get it working, it not supported due to differences from standard ultrasonic range sensors.
