 |
 |
 |
The DroneCAN Airspeed & Baro Sensor is a DroneCAN sensor node for unmanned aerial vehicles (UAVs) that precisely measures differential pressure (airspeed) as well as static pressure (barometric altitude).
¶ Precise Measurement
- Differential pressure for accurate airspeed determination
- Static pressure for reliable altitude and barometric measurements
¶ Maximum Reliability Through Redundancy
The sensor features a redundant DroneCAN connection and can be connected to the autopilot via two independent bus lines simultaneously.
This provides true communication redundancy:
- Parallel connection to two DroneCAN buses
- Continuous communication even in case of cable damage or bus failure
Significantly increased system safety for mission- and safety-critical UAV applications
¶ Engineered & Manufactured in Germany
The DroneCAN Airspeed & Baro Sensor Node is fully developed and manufactured in Germany, representing:
- Highest quality standards
- Reliable industrial manufacturing
Long service life and reproducible performance
¶ Key Benefits at a Glance
- Combined airspeed and barometric sensor in a compact node
- Redundant DroneCAN communication for maximum operational safety
- Seamless integration with common autopilot systems
- Engineered & Made in Germany
This sensor is the ideal choice for professional UAV systems where precise flight data acquisition, redundancy, and reliability are top priorities.
