General Discussion Research

I use D300 pressure sensor with qground controller. But when activate depth hold mode it push drone to surface. How can I solve it?

Hi @vugar333 -
Is this the sensor you are referring to?
While it seems to use the same sensor as the Blue Robotics Bar30, the construction is much different, and seems to rely entirely on epoxy.
Do you have depth values coming from the vehicle ok? If not, the device may not be connected correctly or is faulty. I would recommend reaching out to the vendor that supplied it to you! Best of luck

I test it on different pixhawk, it works. But I don’t know what is wrong with previous pixhawk.

Hi @vugar333 -
Is the other pixhawk the same model?

Yes, same model 2.4.8

Blue Robotics no longer uses this Pixhawk in part because getting reliable hardware performance from it was always a struggle! I would suspect this second unit is faulty…
