Hello,
I tried looking in the wiki, but couldn’t find my answer. I want to use two digital, I2C air speed sensor using arducopter, but I don’t if it’s support, not the configuration steps necessary if its supported

Arducopter doesn’t support Airpseed sensors to my knowledge. Plane and Rover.

Here is an old PR to add that in. But it would need some work to update and test it.

fix #7654
Airspeed sensor can provide more data about copter flight status. … It is important for remote operation or flight beyond line of sight. I need airspeed reading for my current project. So I do it. Thanks @rmackay9 's advices. Tested on my quadcopter (analog airspeed sensor connected to pixhawk ADC 6.6v)
Hi @bnsgeyer , Would you be able to taking a look? Because you mention that you have done it before. Thank you very much.

Just as a note I have PR here to add this that is 85% along the way to being good to go.
ArduPilot:master
← hendjoshsr71:pr/heli_airspeed
opened 08:57AM - 01 Oct 21 UTC
To be added after PR https://github.com/ArduPilot/ardupilot/pull/18838 which mov… es AP_Airspeed usage up into AP_Vehicle
@bnsgeyer
This adds airspeed support to copter and replaces https://github.com/ArduPilot/ardupilot/pull/8430 & Closes https://github.com/ArduPilot/ardupilot/issues/7654
I tried to incorporate most of the comments in the above PR. It does not incorporate any control elements or autocal. This is reporting only.
**Notes**: This PR adds 13.6 KB to copter it is defined out for boards 1MB or lower
**Questions not addressed** in above PR: What happens in the EKF if someone tries to use airspeed?
I tried to make the default ARSPD_TYPE in SITL with Copter to be NONE, but that led to issues with the autotests not holding the param through the restart....???
**Tested in SITL only:**
Type == Analog

Type == MS5525 Weird Data here between mode types
