Airspeed sensor i2c protocol?

I want to make my own custom airspeed sensor, and want to send to data back to pixhawk via i2c.

However, I’m not able to find any relevant documentation about this, nor can I find the source code of the airspeed sensor (is it also open-sourced?).

Can someone point me to some resources about this?? Thank you!!

What do you mean custom airspeed sensor? Most of them are just a differential pressure sensor on a breakout board. For example here’s a driver for the MS5525.

Thank you! This actually answered my question.

Hello sir. I want to use this MS5525 differential pressure sensor. Can you please give me advice on how I use it? I can’t find any resources online on how I actually talk to this sensor.
