Optical Flow Sensor Smart Camera V1.3.1 for PX4 Flight Controller With Sonar

This sensor is designed for direct integration with the PX4 flight stack, including all Pixhawk-series autopilots (Pixhawk 1, 2, 4, 6X, etc.). It communicates via a serial telemetry port and is supported natively in PX4 and ArduPilot firmware for velocity and position feedback in modes like Loiter and Position Hold.

The module includes a dedicated analog input and physical mount compatible with Maxbotix-series ultrasonic rangefinders (e.g., MB1000, MB1200). The sonar provides accurate height-above-ground data, typically up to 5-7 meters, which is fused with the optical flow data in the flight controller for improved altitude hold and landing precision in the absence of barometric or GPS altitude.

Yes. The MT9V034 sensor features large 24µm 'super-pixels' for high light sensitivity, allowing it to function indoors or in twilight without an auxiliary LED. The optical flow processing rate automatically adjusts from 250 Hz in bright conditions down to 120 Hz in darker environments to maintain reliable tracking of ground texture.

The sensor requires a 5V DC power supply and draws approximately 115 mA. It typically connects to your Pixhawk flight controller via a dedicated serial port (e.g., TELEM2) for data and a 5V/GND connection from a power module or regulated BEC. The included cable or pinout follows standard PX4 telemetry/peripheral wiring conventions.
