I was using the following link as a guide to install optical flow on my drone and already have a Sonar installed that is reporting altitude.
I ordered and connected the ThoneFlow 3901U sensor as it looked to be the most economical choice to test it out.
Mission Planner reports value spikes of +1, -2 etc in opt x and y when I have my arm close to sensor and wave but it is inconsistent.
Does this sensor require a lens to work correctly? Can anyone if they have a working setup show me what values to expect since this sensor does not show video output like the PX4Flow to calibrate.
How do can I test this out without flying the drone to have at least an approximation that I am getting correct readings.
Example: To test the range sensor, I can just lift the drone and see the change in values. The opt x and y here don’t show any change if I move the drone.
