What is the minimum sensor size for VisiSens?
The minimum sensor size is not exactly defined and depends on your field of view. You should be able to easily mark the sensor region with a polygon ROI (region of interest) as you will have to use in the software for the calibration process. A 3 x 3 mm piece should be enough for this purpose.
