unfortunately I only have a linux system with ubuntu 20.04 on it right now. afaik it needs \>ubuntu 22.04.

i could try putting the unit in water to see if it returns any value but right now, in air, its returning none.

also as per this post [Is the Ping360 sonar signal harmful to humans? - #2 by EliotBR](https://discuss.bluerobotics.com/t/is-the-ping360-sonar-signal-harmful-to-humans/10285/2) it cannot work in air? im not sure what that means
