Ultrasonic Semsor on aPixhawk

Hardware

Hi all

I know it is possible to attach a sensor to the pixhawk to accurately control the hight the model flies at and units like the Lidar-Lite can be used. But what about the Arduino Sensors like this one

Can they be used as well, if yes how do you connect them.

Thanks for any help with this

and that model is not supported on PixHawk only on APM boards
