Product overview
The CUAV SKYE 2 Airspeed Sensor provides airspeed sensing for unmanned systems in an integrated hardware unit. Its physical architecture combines a pitot tube, SM5391 airspeed sensor, temperature and humidity sensing, an ARM M4 processor, and dual temperature compensation. A linear body design reduces wind resistance, while drainage holes remove excess rainwater during flight. The hardware therefore brings pressure sensing and environmental management together within a 101.9 × 28.2 × 29.9mm body weighing 24.38g, giving integrators concrete dimensions and mass for installation planning.
Integration uses DroneCAN communication, with support for ArduPilot and PX4 and a default supply range of 18–68V. The configuration incorporates a 35W pitot heating system and M4C control that responds to ambient temperature and humidity to support de-icing and drainage. Airspeed measurement spans 0–106m/s, also expressed as 0–381.6km/h, with accuracy of ±1% full scale. The -20–125°C figure describes temperature measurement. IP54 protection is specified for installation on request, making that configuration qualification relevant when procuring the sensor for exposure to rain splash.
