CUAV SKYE 2 Heated DroneCAN Airspeed Sensor

The CUAV SKYE 2 is a heated, all-in-one DroneCAN airspeed sensor for fixed-wing and VTOL aircraft on ArduPilot or PX4. The pitot tube, SM5391 differential pressure sensor and STM32F4 processor sit in one aerodynamic housing, and 35 W of resistive heating keeps the probe free of ice in cold, wet conditions.

Key features

• Wide range: measures 0–106 m/s (0–381.6 km/h) at ±1% FS accuracy.

• Intelligent de-icing: twin resistive heaters regulated from real-time temperature sensing.

• Environment sensing: built-in temperature (-20 to 125 °C) and humidity (0–100%) measurement, with low temperature drift.

• Weather sealing: IP54 when installed to CUAV's instructions, with built-in drainage that clears rain in flight.

• DroneCAN: one CAN cable to the flight controller, no I2C wiring.

Specifications

• Processor: STM32F4 (Cortex-M4)

• Pressure sensor: SM5391, ±6895 Pa

• Airspeed range: 0–106 m/s

• Accuracy: ±1% FS

• Heating power: 35 W

• Sensor supply: 16 V DC from the SKYE2 HV HUB

• HV HUB input: 18–68 V

• Protocol: DroneCAN

• Dimensions: approx. 102 x 28 x 30 mm

• Protection: IP54 (installed per CUAV guidance)

Power runs through the SKYE2 HV HUB, which takes 18–68 V from the flight pack; the first-generation SKYE HUB is not compatible with this sensor.
