# Airspeed Sensor (delete me)

This page describes how to set up and configure the SDP33 airspeed sensor included in the Skynode Evaluation Kit

As with any other PX4-supported peripherals, setup and configuration on Skynode is no different from the official PX4 workflows.

## Wiring

You will need the following components:

* 1x [Airspeed Sensor SDP33](https://store-drotek.com/793-digital-differential-airspeed-sensor-kit-.html)
* 1x Cable *PRIMARY*
* 1x Cable *Pixhawk 4-pin* or the cable that came with the Airspeed sensor
* 1x [Pixhawk Adapter Board](/~/changes/TDRfjBXXgHmxK48cWqay/hardware-integration/skynode/peripherals/adapter-boards.md)

Use the *PRIMARY* cable to connect the Pixhawk Adapter Board to Skynode and then connect the Airspeed sensor to I2C1 (J18) on the Pixhawk Adapter board as shown below

## Configuration and Calibration

* [Power Skynode](/~/changes/TDRfjBXXgHmxK48cWqay/hardware-integration/skynode/evaluation-kit/powering-skynode.md)
* [Connect to it via USB-C or Wi-Fi](/~/changes/TDRfjBXXgHmxK48cWqay/hardware-integration/skynode/evaluation-kit/connect-to-amc.md)
* Open Auterion Mission Control and enable the [Advanced Mode](/~/changes/TDRfjBXXgHmxK48cWqay/hardware-integration/flight-controller-customization/amcs-advanced-mode.md)
* Navigate to the "Parameters" tab and change the parameter `SENS_EN_SDP3X` to 1
* Calibrate your sensor following the public [PX4 docs](https://docs.px4.io/v1.12/en/config/airspeed.html)
