Airspeed sensors are highly recommended for fixed-wing and VTOL frames. They are so important because the autopilot does not have other means to detect stall. For fixed-wing flight it is the airspeed that guarantees lift not ground speed!<br> The for Pixhawk digital differential 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 the APM 2.6 analog airspeed sensor.<br> 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 for Pixhawk Airspeed Sensor Kit enables a resolution of 0.84 Pa, with data delivered at 14 bits from a 24 bit delta-sigma ADC.<br> It also measures temperature to allow calculation of true airspeed from indicated airspeed using the MS5611 static pressure sensor on for Pixhawk.<br> Not influenced by the heat of nearby processing components, it is much closer to the air temperature than with previous analog sensor setups.<br> Supported on all for Pixhawk and PX4 autopilot generation boards, this kit comes with M3 / 6-32 mounting holes.<br> The appearance and color of different batches of products may be different, which will not affect the use.<br> Colour:As Shown<br> Material:Plastic+Metal<br> Package Contents:<br> 1 * Airspeed Sensor<br> 1 * Pitot tube<br> Only the above package content, other products are not included.<br> Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing.
