Matek Digital Airspeed Sensor AS-DLVR-I2C

Description

The Matek AS-DLVR-I2C Digital Airspeed Sensoris a high-precision airspeed measurement moduledesigned for ArduPilot and INAV 7.0+. Utilizing the All Sensors DLVR-L10D, this sensor delivers industry-leading accuracyand is currently the best airspeed sensor supported by ArduPilot.

With an I2C interface (0x28 address), the AS-DLVR-I2Coffers seamless integration with supported flight controllers. It operates within a speed range of up to 227 km/hand a pressure range of 2500Pa, ensuring reliable performance across a -20°C to 85°C temperature range. Its low 5mA power consumption, lightweight 3.5g design, and clear silicon tubing with a Pitot tubemake it ideal for fixed-wing drones, UAVs, and autonomous aircraft.

The AS-DLVR-I2Cis compatible with ArduPilot (ARSPD_TYPE=9) and INAV 7.0+, making it a must-have for precision airspeed measurement and advanced UAV flight control.
