You need to enable the airspeed sensor in Mission Planner | InitialSetup | Optional Hardware | Airspeed.
Note:
Oscillation between zero and small values (2-3) is normal. The airspeed varies with the square root of the pressure, so for differential pressures near zero it varies quite a bit with very small pressure changes, while at flying speeds it takes much greater pressure changes to produce a similar change in speed. If you see mostly 0, 1, 2, with an occasional bounce to 3 or 4, consider it normal. You will not see that sort of variability at flying speeds. As a check, you can take the fleshy part of your fingertip and press it against the pitot tube to raise the airspeed reading up to say 15 m/s. It is easy to see that holding a significant constant differential pressure like this the reading does not bounce around (if you keep constant pressure).
Once you have the airspeed sensor connected, you can use it to control aircraft speed in auto modes. Change the “Cruise” setting in the Basic Tuning screen of Mission Planner:
