Holybro Ardupilot Arduplane Pitot Digital Air Speed Meter / Airspeed Meter Sensor Tube for Pixhawk PX4 Flight Controller     The Holybro Digital Airspeed Sensor has a very low offset, a high resolution and, best of all, does not suffer from the noise induced by long cables and offsets in the ratio-metric output on other airspeed sensors. Supported on all Holybro Autopilot Flight Controller Boards with Ardupilot & PX4.     Featuring a Measurement Specialties 4525DO sensor, with 1 psi measurement range (roughly up to 100 m/s or 360 km/h or 223 mp/h), the Pix32 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 Pix32. Not influenced by the heat of nearby processing components, it is much closer to the air temperature than with previous ana log sensor setups, comes with M3 / 6-32 mounting holes.     Sensor Model Number: MS4525DO-DS5AI001DP I2C Address& 65306;0x28H      Package Includes:     Digital Air Speed Sensor * 1  GH 4pin 150mm cable *1  Molex 4pin 150mm cable *1 Rubber tubing 400mm *1  Pitot tube *1
