MS4525DO Airspeed Sensor With Pitot Tube, Differential Pressure Module For Pixhawk PX4, Accurate UAV Speed Monitoring

Product Description:

- The modified version of airspeed head adopts digital differential pressure sensor, I2C communication, suitable for PIXHAWK, adoting PX4 firmware

- Different from analog differential voltage sensor APM adopts, APM 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 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 Pixhawk and PX4 autopilot generation boards.
