Matek AS-DLVR-I2C Airspeed Sensor

Description: The compact and precise Matek AS-DLVR-I2C airspeed sensor is designed for use in aircraft models, drones, and platforms with flight controllers. This device from Matek offers convenient integration via the I2C interface and functions as an external airspeed sensor for autopilot systems. The sensor is supplied in Ukraine with an official warranty and is ready for use in telemetry and flight control projects.

Compatibility and Firmware

For ArduPilot, this sensor is recognized as ARSPD_TYPE = 9 (I2C-DLVR-10in). As of INAV v.4.1.0 release, official support has not been announced; to use the sensor in INAV, a flight controller firmware build from source code with added support for this sensor is required. Ensure your controller's firmware supports ARSPD_TYPE = 9 or perform a custom build to add support.

Advantages and Applications

Thanks to its small dimensions (20×20 mm) and low weight (3.5 g), the sensor is easily integrated into light and compact platforms. The I2C interface with address 0x28 simplifies connection to modern flight controllers, and the wide temperature range allows the sensor to be operated in various climatic conditions. The Matek AS-DLVR-I2C is suitable for airspeed measurement in flight control systems, telemetry, and avionics calibration, where accuracy and minimal sensor module weight are important.

Integration Recommendations

For accurate readings, ensure correct placement of the Pitot tube on the aircraft body and minimize turbulence around the installation location. Connect 4-5.5 V power, ensuring the controller's power source can handle ~5 mA consumption. Before use, check firmware settings: ARSPD_TYPE = 9 or alternatively, build from source code to add sensor support. It is also recommended to calibrate the sensor under standard installation conditions for maximum accuracy.
