Analog Airspeed Sensor with Pitot Tube for APM

Analog Airspeed Sensor with Pitot Tube for APM

PDF icon Data Sheet227.8 KB

Product now discontinued - replaced with Digital Airspeed Sensor Kit - HERE

This Analog Airspeed sensor is a perfect match for our APM 2.8 Flight Controller, giving you telemetry feedback and a more accurate way for the flight controller to determine airspeed, over just relying on GPS calculated ground speed.

The kit makes use of the MPXV7002 Differential Pressure Sensor, which is designed to measure positive and negative pressure. In addition, with an offset specifically at 2.5V instead of the conventional 0V, this new series allows can measure pressure up to 7kPa through each port for pressure sensing or vacuum sensing.

Included with the sensor is a differential pressure pitot tube and silicone hose. For accurate airspeed measurements, ensure that the pitot tube is located in clean airflow, well away from propeller wash and exhaust.

APM Setup Instructions here.

It's also possible to use this sensor for iNav FCs, instructions here.


  • Low pass filtered
  • Temperature compensated 10° to 60°C
  •  -2 to 2 kPa (-0.3 to 0.3 psi).
  •  0.5 to 4.5V Output

Useful Tips:

  • The kit includes a differential pitot tube that replaces the need for two separate probes. The pitot tube's inner tube that measures the dynamic pressure, and the outer section measures the static pressure.
  • 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 from the fuselage to be outside the prop flow.
  • The airspeed sensor reading is automatically zeroed by the APM during initialisation, so it is good practice during windy conditions to place a loose fitting cover over the pitot tube that shields the front hole and the four small side holes from the wind. This cover should be fitted prior to power on and removed before flight.
  • You can check the airspeed reading with Mission Planner or another ground station. Just blow on the pitot tube and observe the response. In still air 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.
