I connected the bar30 pressure sensor to i2c port of Pixhawk. And when I see the external pressure and temperature values in Q-ground Control, It is showing negative values. How to resolve?

Hello Lahari,

I have the same problem with a Bar-30 pressure sensor, were you able to resolve the issue?

not yet.

Hi @Lahari and @remorakonstantin,

Could you try updating to the latest stable ArduSub version (4.1.1)?

If that doesn’t resolve the issue then you may have a defective sensor, in which case I’d recommend contacting support@bluerobotics.com to see if they have any further ideas, and discuss a replacement otherwise. If you do send an email, please include your order number, or at least a rough order date.
