Description Product Description: The modified version of airspeed head adopts digital differential pressure sensor, I2C communication, suitable for , adoting PX4 firmware Different from analog differential voltage sensor adopts, is not universal 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! The for 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 2.6 analog airspeed sensor. 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 Airspeed Sensor Kit enables a resolution of 0.84 Pa, with data delivered at 14 bits from a 24 bit - ADC. It also measures temperature to allow calculation of true airspeed from indicated airspeed using the MS5611 static pressure sensor on for . 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 for and PX4 autopilot generation boards.
