High Precision DroneCAN Airspeed Sensor - DLVR

High Precision DroneCAN Airspeed Sensor - DLVR（复制） - Holybro Store

Overview

The Holybro DroneCAN Airspeed is an industrial-grade differential pressure measurement module designed for precision airspeed measurement in various UAVs, including planes, VTOLs, and other vehicles. Equipped with the DLVR Digital Pressure Sensor and running ArduPilot AP-Periph Firmware, this module ensures accurate and reliable airspeed data across different flight conditions.

Features

Wide Pressure Range: Supports up to 2500 Pa and 226.8 km/h (141 mph) airspeed measurement for DLVR-L10D. Or 5000 Pa and 320 km/h (200 mph) for DLVR-L20D.
High-Precision DLVR Sensor: Based on ALLSENSORS® DLVR with CoBeam technology, providing high precision and low temperature drift.
High Accuracy: Achieves better than 1% accuracy across a wide temperature range, ensuring reliable and accurate readings in demanding applications.
DroneCAN Protocol: Compatible with both PX4 and ArduPilot platforms.
Aluminum Shell: Durable and reliable construction
Software toggle for CAN termination resistance
