The CORVON KEY TOF 8m module integrates Time-of-Flight (TOF) infrared ranging and optical flow sensing for precise altitude control and obstacle avoidance in drones and robotics. Engineered with multi-sensor fusion technology, it delivers centimeter-level accuracy across 0.1–8m distances while compensating for motion drift. Compatible with UART/I²C interfaces and open-source flight controllers (APM/PX4/INAV), it enables stable autonomous operations in GNSS-denied environments:cite[1].
