3DR PX4 / Pixhawk Airspeed Sensor Kit

Authentic 3DRobotics Product.

This is a stand-alone airspeed sensor kit, including a Pitot Tube, silicone tube and a cable for your flight controller Cube, Pixhawk, etc. (ArduPilot).

Thanks to this module, your autopilot will be able to use air speed based functionalities like automatic landing etc.

This kit uses Measurement Specialities 4525DO sensor with 1 psi measurement range (roughly up to 100 m/s or 360 km/h or 223 mp/h). It has high resolution and low offset which allow registering extremely precise air speed readings. It also measures temperature to allow calculation of true airspeed from indicated airspeed using the MS5611 static pressure sensor on Pixhawk. Since it works I2C, it doesn't not suffer from noise or offsets caused by long cables like for analog sensors. There is also a built-in sensor to allow calculation of TAS (true airspeed) with MS5611 static pressure sensor from Pixhawk PX4.
