Digital Air Speed Sensor Holybro AS1318C w/ PT40 Pitot Tube

Product detailed description

Digital Air Speed Sensor Holybro AS1318C w/ PT40 Pitot Tube

The Holybro AS1318C Digital Airspeed Sensor combines low offset, high resolution, and immunity to cable-induced noise for reliable airspeed measurement on fixed-wing UAVs and autopilot systems. Paired with the PT40 Pitot Tube, it directs air pressure to the sensor for accurate airflow measurement, helping flight controllers maintain stable flight and avoid stall conditions. Built-in temperature compensation calculates true airspeed from indicated airspeed using the flight controller's static pressure sensor, with readings largely unaffected by heat from nearby onboard components. This kit is fully supported on all Holybro and Pixhawk flight controllers running ArduPilot or PX4, and includes M3/6-32 mounting holes for straightforward installation.
