The RI-080 infrared ranging module delivers 8-meter precision measurement using phase-based ranging technology, optimized for robotics, UAVs, and industrial automation. Engineered with a 940nm infrared emitter and advanced signal processing, it achieves ±2mm accuracy in diverse lighting conditions while resisting ambient light interference. The module's compact design and serial interfaces enable seamless integration for real-time obstacle detection, positioning, and height control applications:cite[1]:cite[3].
