Differential Pressure Sensors SDP3x for Drones
Airspeed Sensor Revolutionizes Workflow with PX4 VTOL Drones
In many drone applications the airspeed is important information for reliable and controlled take off, landing and flight. The airspeed is most effectively measured with a pitot tube and a differential pressure sensor. Recently, PX4 integrated the SDP3x differential pressure sensor into an airspeed sensor development kit for VTOL and fixed wing UAV applications, which is fully integrated with the open source autopilot.
The integration includes a full aerodynamic software compensation model for the sensor and pitot tube making it a plug and play solution.
The development kit is now available at our launching partner Drotek. Buy it now.
Lorenz Meier, founder and chief architect at PX4-Pro, says about the SDP3x sensor:
"Most airspeed sensors require calibration before every flight to guarantee accuracy, and are not sensitive enough to produce reliable readings at low airspeeds. The fully calibrated and temperature-compensated SDP3x sensor solves these problems and offers unprecedented accuracy and resolution. The calibration-free setup enables instant launch of VTOL drones, dramatically increasing the user experience for end users. And high sensitivity at low airspeeds allows closed-loop control during the transition phase from hovering to forward flight, increasing the reliability and safety of VTOL drones."
