# Plug to your autopilot

The following section explains how to wire the sensor to your autopilot.

Connect the airspeed sensor to Pixhawk's **I2C** port (or I2C splitter module). Using the rubber tubing, connect the longer extension on the pitot tube to the cone that protrudes from the top of the airspeed sensor board (off the off-white, square section protruding off the top of the board), and connect the shorter extension on the pitot tube to the cone protruding from the base of the board.![](https://github.com/drotek/Docs-Pixhawk3Pro/tree/32dda96b035b92f6eb6f2bdfb9288b10705b6073/images/sdp33-pixhawk.jpg?raw=true)

When you place the **airspeed sensor** in your aircraft, use the **pitot** tube set in the kit (the kit comes with a single tube to measure both static and total pressure). Make sure the holes in the side of the tube are not covered. They should be at least **1 centimeter** out past the nose. First, connect the two tubes coming out the back to the airspeed sensor. The tube coming straight out the back should go into the top port and the tube exiting at an angle should connect to the bottom port on the airspeed sensor. Drill or cut a small hole in the foam and push it through to the front.

If you are using Plane in an aircraft with the propeller in the nose, the pitot tube must be mounted out on one wing, at least a foot away from the fuselage to be outside the prop flow.\
