Serial type airspeed sensor

ArduPlane

Hi everyone, I have an airspeed sensor on which i2c signals from the sensor is converted into uart/serial data. I have connected the airspeed on serial 4 port of my autopilot. I am confused regarding which arspd_type should I select for the same as the arspd_type list doesn’t have any serial type airspeed sensor listed in it. I tried MSP for no good.

Then probably it’s not supported by the firmware.

That’s very unusual. I don’t know of any airspeed sensors supported by Ardupilot that connect via a serial port. I2C, analog, and CAN bus are more common. Could you post a picture showing the differential pressure sensor? Maybe it’s supported, and you can use the I2C output.
