Want to have a very accurate reading of your PIXHAWK airspeed?, then look no further than the Pixhawk Digital Airspeed Sensor which is supplied with its own pitot tube. This MS 4525DO Air Speed Sensor And Pitot Tube Set for Pixhawk must be used in conjunction with the Pixhawk PX4 autopilot system.

This unit has a very high resolution, low offset digital pressure sensor which enables it to register extremely accurate airspeed readings. This sensor does not suffer from noise caused by long cables or from offsets caused by ratio-metric outputs which older analog airspeed systems suffer from.

The Measurement Specialities 4525DO sensor is capable of measuring speeds of up to 100m/s (223mph/360kmh) using a 0.84 Pa with data delivered at 14 bits from a 24 bit delta-sigma ADC. This airspeed sensor also has a built-in temperature sensor to allow the calculation of true airspeed from the indicated airspeed using the MS5611 static pressure sensor on the Pixhawk PX4.

Featuring a Measurement Specialties 4525DO sensor, with a 1 psi measurement range (roughly up to 100 m/s or 360 km/h or 223 mp/h), the Pixhawk Airspeed Sensor Kit enables a resolution of 0.84 Pa, with data delivered at 14 bits from a 24 bit delta-sigma ADC.

It also measures temperature to allow calculation of true airspeed from indicated airspeed using the MS5611 static pressure sensor on Pixhawk. Not influenced by the heat of nearby processing components, it is much closer to the air temperature than with previous analog sensor setups. Supported on all Pixhawk and PX4 autopilot generation boards, this kit comes with M3 / 6-32 mounting holes.

If you are flying multi-copters then you do not require this unit as it is only usable if you are using the fixed-wing code in the Pixhawk.
