Hello noiasca,
Thanks for the link.
I have used that example as well, but the A0221AU sensors I have OR do not work with this code OR do not seem to work properly at all.
They both give a distance of about 1460mm - whatever I do with the sensor itself - and then for no reason start to give more realistic measurements for a while, but never a very precise measurement.
I wonder if the A0221AU sensor and the A02YYUW are exactly the same, or if there are some differences, but I cannot find any information on this question.
thanks for helping and regards,
G.
