PX4FLOW V1.3.1 Optical Flow Sensor – Smart Camera for Pixhawk Flight Controllers

precision optical flow sensor for pixhawk autopilot systems

the px4flow v1.3.1 optical flow sensor is a smart camera module that enables precise position hold and autonomous navigation for pixhawk-based drones without gps. using advanced optical flow algorithms and integrated sonar, this sensor provides accurate velocity and altitude measurements for indoor flight, gps-denied environments, and precision hovering applications.

key features

• optical flow camera – tracks ground movement for precise position estimation
• integrated sonar sensor – mb1043 ultrasonic rangefinder for accurate altitude hold
• gps-free navigation – enables autonomous flight indoors and in gps-denied areas
• pixhawk compatible – direct integration with px4 and ardupilot flight controllers
• onboard processing – dedicated processor calculates optical flow vectors in real-time
• i2c interface – simple plug-and-play connection to pixhawk autopilots
• wide field of view – captures ground texture for reliable tracking

perfect for

• indoor drone flight and navigation
• warehouse inspection and inventory drones
• gps-denied environment operations
• precision hovering and position hold
• research and development platforms
• educational robotics and autonomous systems
