Reliable positioning data under intense sunlight, making it ideal for outdoor use in strong light conditions. PMW3901 optical flow sensor provides accurate horizontal displacement and distance measurement, enabling stable hovering and precise navigation even in positioning challenged environments. Low power consumption of 500 mW supports performance while extending battery life. data output frequency of 100 Hz via UART ensures the flight control module receives timely position and displacement information for adjustments. Designed for integration with flight controllers via UART, delivering realtime position and displacement data for navigation and control. Use scenarios: Outdoor drone inspection or mapping in bright sun where stable hover and reliable positioning are critical. Operations in positioning challenged environments near obstacles or in GPSdenied areas requiring precise navigation. Flight control loops that require frequency updates to enable responsive adjustments and autonomous tasks. Specifications excerpt: Sensor: PMW3901 optical flow sensor for horizontal displacement and distance measurement. Power: 500 mW overall consumption.
