Pixhawk Digital Airspeed Sensor Kit

This Digital Airspeed sensor is a perfect match for the Pixhawk 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.

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 Specialties 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.

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. The airpseed sensor kit connects to the I2C hub on pixhawk 1 and pixhawk 2 boards. However on pixhawk 2 boards you will need a JST-GH connector as this unit ships with a connector for pixhawk v1 boards only.
