The CORVON CV50 is a long-range infrared ranging module built on the direct Time-of-Flight (dToF) principle. It measures up to 50 m with high accuracy, a 100 Hz measurement rate, a narrow <2° field of view, and a 905 nm light source. With a 5–10 cm dead zone and selectable UART or I²C output, it suits UAV altitude hold over varied terrain, long-range obstacle detection, and terrain mapping. Compatible with PX4, INAV and ArduPilot. The module measures 28.5 × 13.6 × 21.4 mm and weighs about 6.8 g.

Thank you for choosing a CORVON product. Please read this disclaimer carefully — by using this product you acknowledge and agree to the following. Because we cannot control how this product is installed, used, or maintained, we accept no liability for any loss or damage arising from its use, and any unauthorized modification is undertaken at your own risk.
Keep the optical window clean and unobstructed — dust, smudges, or a covering film will degrade ranging accuracy. Although the 905 nm source is eye-safe, do not stare into the lens at close range for extended periods. Mount the module rigidly with the lens facing the target surface, and observe correct wiring and polarity on the connector — reversed or mis-wired connections can permanently damage the module. Highly reflective, transparent, or strongly light-absorbing surfaces can affect readings; validate behavior in your environment before relying on it for flight.
