MPXV7002DP Air Speed Sensor And Pitot Tube Set for APM
The MPXV7002DP is a differential pressure sensor specifically designed for airspeed measurement in autonomous aerial platforms, paired with a precision pitot tube assembly for accurate dynamic and static pressure differentiation. This sensor is widely used by UAV developers, drone engineers, and aerospace hobbyists who require real-time airspeed data for flight stability control and autonomous navigation systems. The MPXV7002DP solves the critical problem of obtaining reliable airspeed feedback in APM (ArduPilot Mega) autopilot systems, enabling precise airspeed-hold functions and improved flight safety in fixed-wing aircraft and multirotor applications.
Product Overview
The MPXV7002DP operates on the principle of differential pressure measurement, detecting the pressure difference between the dynamic pressure port (from the pitot tube) and the static pressure port. This differential pressure is directly proportional to airspeed according to Bernoulli's equation, allowing the sensor to output an analog voltage that correlates precisely with aircraft velocity. The sensor features a ratiometric output design with a nominal 5V supply, producing a 0-5V output signal that scales linearly with pressure differential from 0 to 2 kPa, covering typical airspeed ranges of 0-100 km/h for small UAVs. The integrated pitot tube assembly is constructed from durable materials with proper streamlining to minimize measurement errors caused by flow disturbance.
What distinguishes the MPXV7002DP in APM applications is its exceptional accuracy of plus or minus 2.5 percent of full-scale reading and low output impedance that interfaces seamlessly with APM's ADC (Analog-to-Digital Converter) inputs without requiring signal conditioning. The sensor's temperature compensation across the operating range of -40 to 125 degrees Celsius ensures consistent airspeed readings regardless of environmental conditions. The compact form factor and lightweight construction make it ideal for weight-sensitive UAV platforms where payload capacity is critical, while the robust stainless steel pitot tube design withstands moisture ingestion and vibration encountered during flight operations.

- Experimental aircraft and model airplane projects where precise airspeed feedback improves flight stability and enables advanced autopilot features
- Aerial surveying and mapping platforms needing airspeed data for ground speed calculation and mission planning optimization
How to Use
Installation of the MPXV7002DP requires mounting the pitot tube assembly at the aircraft nose or wing leading edge in clean airflow, positioned perpendicular to the relative wind direction and isolated from engine exhaust or propeller wash. Ensure the pitot tube inlet faces directly into the airflow while the static pressure port remains unobstructed. Connect the sensor to your APM autopilot using a 3-wire connection: red wire to 5V power supply, black wire to ground, and yellow wire to an analog input pin (typically A0 or A1) configured as airspeed sensor in the APM firmware parameters.
Calibration is essential for accurate airspeed measurement. In the Mission Planner software, navigate to the Airspeed Calibration section and perform a ground calibration with the aircraft stationary to establish the zero-pressure baseline. For in-flight calibration, fly the aircraft at known airspeeds (determined via GPS ground speed and wind estimation) and adjust the airspeed calibration parameters until the displayed airspeed matches actual flight conditions. Verify sensor functionality by observing voltage output on a multimeter during pitot tube pressure application, confirming the 0-5V output scales linearly with applied pressure. Periodically inspect the pitot tube for blockages from insects or debris and clean gently with compressed air to maintain measurement accuracy.
Frequently Asked Questions
What is the difference between dynamic and static pressure in the pitot tube assembly?
Dynamic pressure is the pressure exerted by moving air as the aircraft flies, captured by the forward-facing pitot tube inlet. Static pressure is the ambient atmospheric pressure, measured through small side ports on the pitot tube body that remain perpendicular to airflow. The MPXV7002DP measures the differential pressure between these two sources, which is directly proportional to airspeed. This differential pressure increases with the square of velocity, allowing accurate airspeed calculation across the sensor's measurement range.
Can the MPXV7002DP measure airspeed in high-altitude operations?
Yes, the MPXV7002DP functions effectively at high altitudes up to 10,000 feet or higher. The sensor measures differential pressure, which is independent of absolute atmospheric pressure, so altitude does not directly affect accuracy. However, true airspeed increases with altitude at constant ground speed due to thinner air, so your APM firmware should account for air density corrections if precise true airspeed is required for advanced flight control logic. The sensor's temperature compensation helps maintain accuracy across the temperature variations encountered at different altitudes.
How do I prevent pitot tube icing in cold weather operations?
The MPXV7002DP sensor itself operates reliably to -40 degrees Celsius, but pitot tube icing can block airflow and cause measurement errors. For cold weather operations, consider installing a pitot tube heater element that draws power from your aircraft's battery system to prevent ice crystal formation. Alternatively, use a heated pitot tube design specifically manufactured for icing conditions. Ensure your airframe design positions the pitot tube where it receives maximum airflow and minimal moisture accumulation. Monitor airspeed readings for sudden drops or erratic behavior, which indicate potential icing.
What cable length can I use between the sensor and APM without signal degradation?
The MPXV7002DP's low output impedance below 1 kOhm and ratiometric design allow cable runs up to 10-15 meters without significant signal degradation, assuming standard shielded twisted-pair cabling. For longer distances, use twisted-pair shielded cable with the shield grounded at the APM end only to minimize noise pickup. Keep sensor power and signal wires separated from high-current motor or ESC wiring to avoid electromagnetic interference. If cable runs exceed 15 meters, consider using a signal conditioning board or flying a secondary sensor closer to the autopilot.
