hobbyant PX4 Differential Airspeed Pitot Tube + Pitot Tube Airspeedometer Airspeed Sensor for Pixhawk PX4 Flight Controller
Brand:hobbyant
The 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.
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 Pixhawk 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 Pixhawk.
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 all Pixhawk and PX4 autopilot generation boards, this kit comes with M3 / 6-32 mounting holes.
The modified version of airspeed head adopts digital differential pressure sensor, I2C communication, suitable for PIXHAWK, adoting PX4 original firmware.
Different from analog differential voltage sensor APM adopts, APM is not universal.
Note: if you cant use the item, please change SDA->SCL,and SCL->SDA
