D300 Depth and Water Temperature Sensor

beyza nur yağcı

Hello,

I connected the DEGX D300 I2C pressure sensor to Pixhawk. It is stated that the sensor is compatible with ArduSub, but I could not clearly understand how I can read this data in my own software and control the ascent motors accordingly.

My goal is as follows:
I want to control the ascent motors via Arduino Mega by receiving the depth data from the pressure sensor via Pixhawk.

My question is as follows:
Can I access this sensor data via Mavlink? If yes, with which message can I read this pressure/depth data via Mavlink? Also, what kind of Mavlink messaging structure should I set up to receive this data via Arduino Mega?

I would be very happy if you could help me with an example message structure, suggested message type (e.g. SCALED_PRESSURE, VFR_HUD, ATTITUDE, etc.) and how to correctly decode it.

Thank you,

Hi Beyza, I couldn't catch if you are adding arduino mega just for depth hold. Ardusub and Mavlink is capable for it without the need of an arduino.
Can you give some additional information?
