First of all, what has happened to bit-tech? There used to be an electronics forum, but now I can't find it. On to my question. I have been searching for a small airflow sensor (as small as you get them, really). The only airflow sensors I have found when googling have been larger ones for use in cars, but I need one that is way smaller (let's say maximum of 1x1x1 cm (or smaller). Does such a sensor exist, and does anybody have any part numbers of links?
