The CORVON CV0850 is a compact infrared ranging module built on the direct Time-of-Flight (dToF) principle for short-range distance measurement. It ranges from 20 mm to 8 m with a narrow <3° field of view, a 50 Hz measurement rate, and an eye-safe 940 nm light source. Its small 20 mm minimum spot and strong ambient-light immunity suit UAV altitude hold, robot and AGV obstacle avoidance, and proximity sensing in low-power systems. Distance is output over UART or I²C, making it a drop-in fit for PX4, INAV and ArduPilot. The module measures 20.0 × 16.5 × 6.7 mm and weighs about 1.8 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 940 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.
